WIRE TECHNOLOGY

All wires are made from steel rods through a drawn process. Steel rods are unprocessed, raw material with lower initial properties and quality specifications than drawn wires.

Processing the rods eliminates the variation in diameter and makes a perfectly rounded wire.

One important problem is that the uniformity of a rod's diameter consistency varies along its length. This inconsistency creates a loosely woven screen cloth with wires that rub against each other at the weave point, resulting in premature wear or failure.

MAJOR uses drawn wires for all of its screening media. Many competitors use steel rods to produce their screen cloth, especially in larger wire diameters.

WIRE QUALITYWire quality plays an essential role in a screen’s performance and is measured by three key factors: hardness, tensile strength and ductility. The level of performance of each factor is dictated by the wire’s chemical content and by its molecular structure, which is influenced by the type of process creating the wire.

CHEMICAL CONTENT

In principle, the higher the carbon and manganese content, the better the wire. But, to get a true high-performance wire, both element levels have to be balanced in an optimum recipe specific to an application. Unbalanced levels could negatively affect the wire’s performance.

The key chemical elements contributing to a wire’s performance are:


The effective quality of wire depends on the right balance of the three factors. MAJOR has developed the best recipe of chemical content and wire-making process to optimize all factors for all of its wires.

MAJOR validates, through close collaboration with the steel mills and its wire manufacturers and through its own specifications and laboratory quality controls, that all wires used in making MAJOR screens have the optimum content and recipe of carbon and manganese per application.

Resistance to abrasion and wear. The harder the wire, the greater its wear life.

Capacity to support stress and to be formed without breaking or losing its properties.

If a wire is not ductile enough, it will break or have micro-breakage when crimped. If it is too ductile, it will have a low tensile strength.

HARDNESS

DUCTILITY

Resistance to failure/breakage under stress. The higher the tensile strength, the better the wire can resist stress and impact.

WIRE PROCESSES

This process is an attempt at improving the molecular structure. The wire is drawn through a conic die, then heated and then oil quenched.

Result: This process provides unsatisfying results. It improves the hardness and tensile strength of the wire, but greatly deteriorates the molecule structure and its ductility (the wires break more easily under impact and are more subject to micro-breakage when crimped).

OIL-TEMPERED PROCESS

ROD

OIL MIST FOR COOLING

This is the basic process to make a wire by having the rod drawn through a conic die to a specific dimension (in one or several sequences).

Result: This basic process has a limited impact on the molecular structure. It improves the wire’s tensile strength, but not its hardness or ductility. It is mostly used to make low-quality and economical wires or very high-gauge wires, which already have maximum hardness and ductility.

HARD OR DIRECT-DRAWN PROCESS

ROD HARD-DRAWN CARBON WIRE

ELONGATED MOLECULES

This process is the ultimate way of improving the molecular structure. The rod is heated first and then cooled at a controlled temperature to optimize the molecular structure before being drawn through a conic die.

Result: This process gives the best results, providing optimum tensile strength, hardness and ductility.

STAINLESS STEEL

By adding 11% or more chromium to steel, a stainless steel alloy becomes non-staining under most conditions that corrode carbon steel. In addition, alloys containing chromium and nickel are not magnetic when they are annealed, so more material passes through, instead of sticking to the wire.

Stainless steel woven wire is available in .025-inch (.63 mm) to .375-inch (9.5 mm) diameters in two types:

Type 304:

The most common type of stainless steel wire available, it is sometimes referred to as “18-8” (18% chromium, 8% nickel). Type 304 is comparable to high-carbon wire in ductility, wear resistance and tensile strength. It withstands outdoor exposure without rusting and resists oxidation at temperatures up to 1,400 ° F or 760° C.

Type 316*:

This wire is stabilized by the addition of 2% molybdenum. Like Type 304, Type 316 is an “18-8” alloy, but it has better resistance to pitting and corrosion than Type 304 where brines, sulphur-bearing water or chlorides are present. It also has the valuable property of high tensile strength at elevated temperatures.

* For special orders with extended lead times.


MAJOR uses only the highest quality of stainless steel wires with the highest tensile strength.


SCREEN MANUFACTURING PROCESS

Over and above the quality of the wire, the quality of a screen media also depends on the manufacturing process used. The 3 key performance factors at the manufacturing level are:

OPENING TOLERANCEAligning wires to make a specific size opening is a process with a varying level of accuracy. ISO standard allows for a wire opening tolerance larger than 3%, meaning that openings can vary from each other within that limit. Many screen manufacturers don’t comply with ISO standard, and have a high degree of variance in their openings, therefore contaminating the end product.

SHAPE AND SIZEAll screens must respect strict quality specifications for length, width and squareness to ensure proper performance. Inconsistency in these factors will result in inefficient screen installation, causing early failure.

CRIMPINGMost wires need to be crimped before being used to make a screen. Crimping is a mechanical process where the wire is formed by going through cog-wheels. Quality and condition of the cog-wheels are critical to the wire integrity. Damaged or wrongly positioned teeth on a cog-wheel will create micro-breakage on the wire or will result in loose wires when woven, causing premature failure.


MAJOR screens are manufactured with a stringent wire opening tolerance of + or – 3%, making them an industry-leading standard.

MAJOR screens are made using high-precision robotic tooling throughout all manufacturing plants, and following the highest ISO standards.

MAJOR uses only the highest quality cog-wheels and performs a strict quality control of their condition for every single production it runs, ensuring the perfect integrity of its wires.

SCREENING EFFICIENCY

Screening is the action of separating material to eliminate undesired particles and/or splitting material into different sizes. When screening, there are two principles in action that determine screening efficiency:

OPEN AREAThe surface aperture of a screening media that lets material pass through, pulled by gravity.

• Open area varies with the screening media type, and affects the tonnage of material that can be processed on a screen deck.

• The more open area, the more screening capacity.

• On screening boxes with multiple decks, the relation of open area and material gradation between the decks is an important efficiency factor that needs to be balanced.

STRATIFICATIONA natural physical phenomenon where, under vibration, coarse material rises to the top and the fine material falls to the bottom.

• The faster the stratification (the higher the vibration), the greater the quantity of fine material that can pass through the open area.

• Vibration is essentially induced by the stroke of the screen box (measured in RPM) and ranges typically between 500-1,000 strokes per minute (and up to 4,200 for high-frequency equipment).

• Vibrating Wire Screens (active media, compared to woven wire, polyurethane and rubber, which are rigid and static) can speed up the stratification process by inducing high-frequency vibration to the material (6,000-10,000 per minutes), adding to the basic strokes of the screen box and letting more material pass through than any other media.

TYPES OF SCREENING MEDIA

There are different screening media available on the market, which provide different levels of screening performance.

WOVEN WIRE SCREENSThese are the most common screen type used in the world. They are the least expensive, they can provide a good open area, but have a low stratification capacity and the shortest wear life.

FLEXIBLE RUBBER OR POLYURETHANE SCREENSThese screens aim at improving the stratification process by using semi-rigid rubber. Because of the thickness of the material, they have a limited effect on the stratification process and still provide low open area.

SOLID POLYURETHANE OR RUBBER SCREENS/PANELSThis media provides a longer wear life, but has a very low open area and stratification capacity. To compensate for the lack of capacity, producers must install larger screen boxes, therefore increasing their investments (fixed assets) and operating costs. Also, even though polyurethane panels have a longer wear life, they can have a limited effective wear life when tight specifications need to be met, due to usage, as explained in the illustration below:

VIBRATING WIRE SCREENS AND PANELSThis is the ultimate innovation in screening media. Wires are not woven and instead are individually held by cross polyurethane strips which can be highly tensioned, allowing them to vibrate at high frequencies under material action. This speeds up the stratification process while providing the maximum open area. It also provides the lowest cost per ton with a high-yield production capacity, while eliminating blinding and pegging issues.

HIGHER SCREENING EFFICIENCY

STRATIFICATION FLEX-MAT vibrating wires add a high frequency vibration (6,000 to 10,000 cycles per minute), on top of the standard vibration of a screen box, which is around 800 cycles per minute.

Compared to woven, polyurethane or rubber screens, which are rigid and static media, the incremental frequencies induced by FLEX-MAT vibrating wires accelerate the natural stratification process of the material bed for maximum throughput, with no carryover, resulting in a high-quality retained product.

OPEN AREA FLEX-MAT offers the best open area for more throughput:

• No cross wires

• A smaller wire diameter, due to higher quality of the optimum patented wire and the flat screening surface

• Widest range of wire diameters per opening

FLEX-MAT provides more screening efficiency than any other screening media, with up to 40% more throughput and 5 times more wear life. It also eliminates blinding, clogging and pegging issues, while providing precise product separation and reducing or eliminating the need for washing.

MOREWEAR LIFE

FLEX-MAT offers a longer wear life than woven wire screens and depending on the application, outlasts polyurethane and rubber media.

• The flat surface offers 100% of surface wear, compared to only the upper “knuckles” of woven screens.

• The even wear of the wires, maintain their the opening within specification, as compared with polyurethane panels, which lose their opening specification with wear due to the slight “V” shape of their opening.

• The vibrating effect of the wire accelerates material passing on all decks (less material on the bed), and causes the material to “micro-jump” and hit the wire straight on, instead of sliding and chipping away at the wire.

• The elimination of blinding, pegging, and clogging reduces the wire degradation.

• The angle alignment on the square model (Series D) limits the impact on the wires facing the flow.

STRIPS, OVERLAPS & SIDE SEALS

The addition of a heavy-duty strip shield is ideal for heavy loads, abrasive rocks, scalping applications, large-sized material and larger openings.

Increasing the size of the standard strip can also reduce material dispersion to the sides by making stronger channels along the screen.

If a larger strip size is required, please request it when submitting a quote.

Increase the size of the standard strip (1/8" or 1/4") or (3.175 mm or 6.350 mm ) to a 1/2" or 12.7 mm strip to extend the screen’s wear life or move up to the heavy-duty strip.

For Series D and Double Wire, the wire opening can also be taken by measuring the diagonal “side to side” measurement (as shown on the left).

To obtain precise opening values for Series S, use a pin measurement in the first full opening next to the lime-green strip, where the wires are stable and stay firmly in place.

The screen's opening is measured by the distance between the wires.

For all FLEX-MAT wire types, the exact wire opening is read by placing a PIN (circular measuring bit) inside the opening. This provides a more accurate measure of the opening than with a wire gauge, measuring tape or caliper.

HOW TO MEASURE OPENINGS


Tensioned screen sections with overlaps, installed on a split-deck with one hook UP and one hook DOWN (most common configuration). Overlaps can only be fitted on one side, right or left.

INSTALLATION INSTRUCTIONS >

28

1. BEFORE INSTALLATION

INSPECT YOUR FLEX-MATFLEX-MAT requires a special manufacturing process. If wires are not lined up correctly when the screen is received, it will be corrected after tensioning.

DON’TS

• Do Not lay screen cloth on stockpiles and other uneven surfaces.

• Do Not stand screen cloth on its side for storage – damage may occur. Store flat or hang the cloth.

• Do Not walk on screen cloth.

• Do Not throw screen cloth on the ground.

• Do Not bend screen cloth.

• Do Not over-tighten when using an impact wrench on wire diameters less than 0.148" or 3.8 mm.

• Do Not expose screens with polyurethane strips to heat in excess of 176˚ F or 80˚ C.

DO’S

Check the following screen machine problems. They will affect Flex-Mat performance.

• Are the crown bars worn, distorted or asymmetrical?

• Are the clamping rails thin or bent?

• Are you sure the “U” channel rubber is fully engaged in the steel bar?

• Are the coil and leaf springs weak or broken?

• Are there cracks, broken welds or loose bolts anywhere in the screen box or screen deck?

• Is your feed to the screen box hitting the feed

box?

Repair all of the above BEFORE proceeding!

2. INSTALLATION

FORGET TENSIONING! S-T-R-E-T-C-H YOUR FLEX-MAT

REPLACE THE CROWN BAR RUBBERInstall new crown bar rubber with each new set of FLEX-MAT, or it will not sit properly on the crown bar, causing cloth breakage.

THIS IS NOT YOUR TYPICAL SCREEN CLOTH PRODUCT.It Must Be Handled and Installed Carefully.

If your customer’s previous woven wire cloth was breaking or prematurely wearing and you are not sure why, contact your Terriroty Manager before installing the FLEX-MAT.


Loose wires before installation.

The tensioning of the cloth will eliminate the slight loose wires and differences in openings once correctly installed.


D and S StretchingTighten the Center Hold-DownBar before the Side Clamp Bar (if applicable)

Check for proper Polyurethanestrip location at all supports

Need clearance of ½" or 12.7 mm after installation is complete

LINE UP AND DO THE STRING TEST

1. Run a string from side-plate to side-plate over the screen crown bars.

2. Pull the string tight.

3. Check for any gaps between the string and the crown bars.

4. If there are gaps, then the height of the crown bars must be corrected.

Must be corrected

Breakage will occur if gaps are not fixed.

LINE UP THE POLYURETHANE STRIPS.

• The polyurethane strips on FLEX-MAT screen cloth MUST line up with the screen crown bars.

• If they do not line up, the screen will be less efficient and the life of the screen cloth could be shorter.

ONLY USE BOLTS – NOT RUBBER DONUTS, WEDGES OR SPRINGS

• Check to make sure that your screen box is outfitted with bolt-type fasteners.

• Check the bolts for stripping, correct length and rust.

CHECK THE WIDTH (SIDE TENSIONED MACHINE)

• Does the width of the screen cloth, outside to outside of the hooks, allow sufficient room for stretching the cloth during installation? Look for ½" to ¾" or 12.7 mm to 19.05 mm clearance on each side after installation is

completed.

CHECK THE LENGTH (SIDE TENSIONED MACHINE)

• Does the length of the screen cloth MATCH the length of the clamping rails? If they do not match, do not install or you will have screen cloth breakage during production!

CHECK THE SCREEN LEDGE – CLEAN THE LEDGE ANGLE

• Remove accumulated fines from the ledge prior to installation of new FLEX-MAT.

PUSH CLAMP BARS INTO HOOKS FOR A SOLID FIT

• Always tighten the inner clamp rail bolts first on both sides at the same time, then the outside bolts.

WIRE BREAKAGE MAY OCCUR IF FLEX-MAT IS NOT STRETCHED TIGHT

TEST – Push thumb down hard on cloth. Must be tight (similar to the surface of a drum), with little or no deflection of wire.

IF EQUIPPED WITH OVERLAPS

Starting at discharge end, overlaps should be placed on top of the cloth preceding it.

Figure A30

SERIES T INSTALLATION

• Install and tension the same as regular woven wire cloth.

• Tighten the center hold-down bar first, if applicable.

• Remember to begin tensioning from the center point on the screen cloth to both ends of the cloth.

• Stretch the FLEX-MAT until it is “tight as a drum” – it should not flex when pressed.

• Run the screen with no load for a few minutes and recheck tension.

• Run the screen loaded for two hours and recheck tension.

SERIES D & S INSTALLATION

If you have center hold-down bars, tighten them first after positioning the cloth properly. (See Figure A on page 30).

1. Stretch the FLEX-MAT until it is “tight as a drum” – it should not flex when pressed.

2. Alternately tighten the clamp bar bolts on

both sides of the screen.

Tighten screen from both sides at the same time. Begin at the center and work towards each end.

Start by running the screen without a load for a few minutes; stop, stretch the screen cloth, and then repeat these steps several more times. The vibrations help regulate the tension by allowing the screen to slide on the rubber mountings, and may also help eliminate any slight differences in the gap between the wires, in order to obtain a perfectly flat surface.

Should a wire become deformed in handling, causing an opening of the crimp, (and stretching is insufficient to restore the mesh), you must release the tension and repair the crimp using a pair of needle-nose pliers. Then proceed as above for re-stretching the screen cloth.

After 2 to 4 hours of operation with the screen under load, recheck the screen tension to see if it is “tight as a drum,” and re-stretch if needed.

Note: Continued blinding problems can occur when cloth is not stretched tightly enough.

• When screen cloth is too loose, the polyurethane gets black marks on its underside and wires can break.

• If polyurethane strips fail to line up perfectly with crown bar supports, the cloth wires can break.


In order to obtain the longest lifespan, FLEX-MAT must be stretched gradually during installation by adjusting the tension 3 or 4 times.

ROUTINE MAINTENANCE

Check the fit of the FLEX-MAT screen cloth frequently.

Re-tighten any loose clamp bar bolts to take up for any wear of the screen cloth.

Make sure the cloth remains properly tensioned or stretched “tight as a drum.”

3. TROUBLESHOOTING

When FLEX-MAT isn’t working properly:

CHECK THE SCREEN CLOTH APPLICATION

• Are the FLEX-MAT wires stretched and tight? Loose panels could break wires, reduce the wire's life and possibly cause blinding.

• Use patented wire for very abrasive products.

• Use stainless steel wire for corrosion or blinding.

• Is the wire diameter light enough to solve the blinding problem, but heavy enough to carry

the expected impact and load?

CHECK THE OPERATION OF YOUR SCREEN MACHINE

SCREEN BOX

• Is it the correct screen box for the application?

• Is the machine transversely level?

• Are there any obstructions to free movement of the screen box?

• Do all decks have screen cloth installed to provide rigidity?

• Is the screen operating at the manufacturer’s recommended speed and throw?

CLAMPING RAILS

• Are the clamping rails in the same configuration as the original equipment?

• Are the clamping rails the same length as the screen cloth?

• Is the hook type and size correct for the clamp rail?

FEED MATERIAL

• Is the machine being fed as close as possible to the feed end of the machine? Feed should be dropped onto a feed box and not directly on the screen cloth.

• Is the fall of the feed kept to a minimum?

• Is the feed spread evenly across the screen deck?

• Is there matted material on the screen cloth that acts as a counterweight, lifting the screen cloth off the crown bars?

SPRAY BAR NOZZLES

• Are the spray bar nozzles clear of the screen cloth?

• Are the spray bar nozzles plugged, or are the stream spreaders worn?

• Does high-pressure water hit the screen cloth in a concentrated area?

• Does a sluice box drop a high volume of water onto the screen cloth?

CHECK YOUR INSTALLATION

• Go back to page 29 of this installation section and make sure you have followed all of the procedures properly and thoroughly.

FLEX-MAT is NOT woven wire. It requires special attention.

INSTALLATION CHECKLIST Polyurethane strips are perfectly lined up over crown bar supports.

There are no gaps between strips and crown bar supports.

The center hold-down was tightened first.

The clamp bar bolts were alternately tightened on both sides of the screen, starting from the center of each clamp bar.

The screen was “tight as a drum” tested for tight wires (no deflection on wires).

Bolts were re-tightened after 2 hours of running with material.

Do not install if using “J” bolts

Problems that cause breakage

Correct installation


INSTALLATION FOR OVERLAPS

Discharge End

Starting at the discharge end, overlaps should be placed on top of the cloth that precedes it.

IMPORTANT DO NOT install Flex-Mat if crown support heights are not correct

or asymmetrical.

DO NOT install Flex-Mat if customer is currently using “J” bolts. These indicate a problem with the crown that needs to be fixed first.

STRETCH FLEX-MAT as “tight as a drum” so that the heavy end of a screwdriver or hammer will bounce off of the screen cloth.

READ the complete FLEX-MAT installation instruction found in the plastic bag with your shipment.

Screen is too flat or the material has not been cleaned off of the hook ledge.

Screen does not fit tightly against all crown supports.

Screen is not stretched tightly enough to lie flat on all crown supports.

Polyurethane strips do not line up perfectly on all crown supports. Cloth is pulled to one side, or the strips weren't measured correctly.

GREATER OPEN AREA

TRUE OPEN AREA CALCULATION

Polyurethane or rubber modular panel open area is calculated based on the entire surface area of the panel, providing the “True Open Area.”

• Do not use “Relative Open Area,” which is calculated only on the area where the holes exist and not on the full panel. Refer to the FLEX-MAT Modular Specification Form found on MAJOR's digital library to find out the “True Open Area,” per specification and panel type.

• To calculate the “True Open Area” of polyurethane or rubber panels, follow this calculation:

surface of a hole number of holes (width x length) X (per panel)

surface of the panel (width x length)

WIRE-TO-WIRE

To prevent product contamination, MAJOR recommends the use of an overlap on all OptimumWire screens with openings of 3/8" or 9.5 mm or smaller when there are no cross-members at the junction point.

Overlaps on screens with wires greater than 0.192" or 4.80mm in diameter can cause installation problems and breakage. For larger-diameter wire screens, when there are no cross members at the junction point, it is recommended to use FLEX-MAT screens with an overlap.

For standard sheets of 48" or 1219.2 mm and 60" or 1524 mm long and an opening greater than 3/8" or 9.5 mm only, MAJOR has developed the “wire-to-wire” feature, which allows for the wire’s length at tail ends, to be equal to or smaller than 1/2 (half) of the screen's openings.

This ensures that the dimensions of the joint openings are the same or smaller than those of the screens, eliminating possible product contamination and the need for overlaps.

TIPS FOR THE ASSESSMENT

MAJOR / TEMPLATES

Determine the best audience for your assessment. Plant managers and quality managers are motivated to have an assessment performed. In larger companies, managers or buyers welcome the initiative. Identify the exact needs of your client at this stage. Managers want ways to improve productivity and lower costs per ton. Emphasize that the purpose of the assessment is to help efficiency and production of the plant. Take the time to talk about the assessments performed for others and how they have generated tangible results. Discuss any concerns about the assessment (people problems, etc.) and confirm that all information learned will be kept confidential.

PLANNING FOR THE ASSESSMENT:

Be clear about how much time is needed to perform the plant assessment on each machine. If they say no, you may not be speaking to the right person.

SET AN APPOINTMENT:

Surveys or interviews should be made with the plant managers, the operations managers and the operators of the targeted site. If possible, it is recommended that you interview the management prior to conducting the field assessment. This will allow you to obtain some valuable insights and collect a variety of data that will be beneficial when it comes time to document the report and assess the potential value of the improvement that can be deployed at that location.

PRIOR TO THE ASSESSMENT:

Come prepared with all the proper PPE and tools. If possible ask to see the boneyard to better determine problem areas. While there, check their inventory to see who supplies them. Check to see if there have been any new problems. Often you will receive more orders on this follow-up visit. Always identify which machine you are getting on/inside. Find what needs to be improved and take photos to support your effort. Always take pictures of what works well. The assessment doesn’t always have to be negative. You will probably find situations like the ones in the Screen Maintenance Seminar.

CONDUCTING THE ASSESSMENT:

Schedule a 1-hour appointment to present the assessment report. Make the appointment within 5-10 days from the assessment's date. Know the names of all attendees to prepare a copy for everyone. With the electronic plant assessment template, identify the company, the people you spoke to, the assessment date and a brief description of the material, sizing, etc. Prepare the visual report by inserting the pictures taken during your visit and a description of your observations and solutions beside each image. The content should cover your observations and propose solid recommendations supported by visuals whenever possible.

AFTER THE ON-SITE PLANT ASSESSMENT:

This is the most important part of the assessment. You need to have their undivided attention. Do not just hand over a document. You need to sit down and discuss the assessment in detail. Present your assessment report and write down all comments and concerns, as well as what they are agreeing to implement. If the client agrees with your recommendations, decide on the next steps with him. You may not have a better window the close on the sale of your products. If you had requested a quote, present your proposal and highlight the potential value improvement opportunity. If you did not have a formal proposal, get a quote to them in 48 hours or less. Then follow-up with a visit to present the business opportunity.

PRESENTING THE ASSESSMENT:

Make a point to follow up with the customer to discuss the benefits that your client has seen since the assessment and the installation of MAJOR's products. Allow sufficient time, (up to 4 weeks), to track the performance and highlight the improvement. Offer training if you feel this would be useful. Inspect the installation to ensure the expected benefits will be delivered. Don’t forget to use the Screening Performance Guide (Checklist).

FOLLOW UP:

At this stage, you have moved on with your customers. Always assist your customer with the first installation and take the opportunity to train their operators on the Screen Maintenance Simplified Seminar.

All three major rock types are formed from the other rock types. Rocks are eroded by water, wind and ice to form sediments.

Buried sediments are hardened into sedimentary rocks.

If the rocks are buried very deeply, they may become heated and squeezed into metamorphoric rocks.

If rocks are heated enough to melt, they become magma. When magma cools, it forms igneous rocks.

Reinforced edges A formed hook on the tensioning edge of a screen panel that is strengthened with the addition of sheet metal.

Retention The ability of wire cloth (wire mesh), as a filter medium, to prevent the passage of solids.

Rock (stone)Rock is a natural material that forms the crust of the earth. There are three broad categories of rock distinguished according to their origins; igneous, sedimentary and metamorphic rocks.

SandSand is a granular material in the range 0.06mm to 2mm. In Europe, ‘sand’ is used for fine aggregates with a top size of 4mm.

Scalping deckThe top deck of a screen box for the removal of the finer fraction of feed with the objective of rejecting damaging material.

Scalping A sizing process separating the very first cut of the incoming material with the sum of all its grades. Scalping refers to removing the largest size particles. This includes enormously large particles relative to the other particle sizes.

Screen A particle sizing device consisting of a surface that is perforated by apertures of characteristic size and shape.

Screen box / Screening machineA screening machine consists of a drive that induces vibration, a screen media that causes particle separation, and a deck that holds the screen media and the drive and is the mode of transport for the vibration.

Screen clothA woven screen is made of wire mesh spaced to specific apertures of uniform size and shape made of any primary metal or metal alloy wire that is suitable for weaving.

ScreeningScreening is a sizing operation effected by a mechanical process which stratifies particles according to screen media opening size.

Screening capacityAmount of material passing through the screen deck in TPH.

Screening efficiencyThe percentage of material that falls through a screen compared in relation to the total amount of material in the product stream of that size.

Screen mediaScreen media is a replaceable wear surface that can be made up of a vast number of configurations based on material types, aperture sizes and styles, fixing systems and surface features, Some material types can be steel, stainless steel, rubber compounds, polyurethane, etc.

Separation size⁄split sizeParticle size at which feed separates into two products (coarse fraction and fine fraction).

Shute wires The wires running the short way of, or across the cloth as woven. (same as “shoot” or “weft” wires).

ShroudA folded metal sheet on two ends of a woven wire screen that is heated and shaped to the required hook style.

Side panThe wall sides of a screen box where screen decks are attached.

Side sealA polyurethane or rubber strip at the side of a wire screen designed to butt up against the pan walls to prevent contamination through the sides of the screen box.

Side-tensioned Edge preparation on a screen surface allowing it to be stretched at right angles to the direction of material flow.

Sieve A device with meshes or perforations through which finer particles of various sizes may be passed to separate them from coarser ones.

Single shuteA woven wire mesh with single wires running the short way of, or across the cloth as woven.

Slotted openings Wire cloth (wire mesh) with rectangular openings that allow the maximum open area and tend to prevent blinding or plugging .

Sluice boxA box with riffles along the bottom, used to trap heavier gold particles as water washes them and other material along the box.

TERMINOLOGY AND ACRONYMS (CONTINUED)

94

MAJOR / GENERAL

Split deck A side tensioned-screen deck divided to allow two individual screen panels to be installed across the width of the deck.

Spray bar nozzleNozzles attached to a horizontal tube used for spraying water over a screen deck.

Spray nozzleA spray nozzle is a precision device that enables dispersion of water into a spray for washing gravel in screening plants.

Spring-loaded boltA threaded bolt with a spring and nut to fasten and tension the screen media to a deck installed from the outside of the walls of the screen box.

StratificationThis phenomenon occurs as vibration is passed through a bed of material. This causes coarse (larger) material to rise and finer (smaller) material to descend within the bed. The material in contact with the screen cloth either falls through a slot, blinds the slot or contacts the cloth material and is thrown from the cloth to fall to the next lower level.

StringerStructural girders in the framework of the deck of a screen box to create a flat deck for modular panels.

StrokeThe shape and amplitude of the motion of a screen box (circular, oval or straight line strokes).

Stroke angleStroke angle in a screen box has an effect on the material amplitude and rate of travel.

Square hook The formed hook on the tensioning edge of a screen panel formed in the shape of a “U” or square, with two right angles.

Square mesh Wire cloth with the mesh count and wire diameter that is the same in both directions.

Support barsMetal bars at regular intervals to create a crowned curve on a deck of a screen box.

Tail endsThe ends of the woven screen opposite the hooked sides that butt against the next screen on the deck.

Tempered wireWire that is heated and oil quenched after drawing.

Tension, tensioned, tensioningThe process of stretching something tight.

Tensile strength The ratio of maximum load to original load to original cross-sectional area. Also called ultimate strength.

ThrowA lurching action in a screen box that throws the material forward and up. As the machine returns to its base state, the material falls by gravity to a physically lower level.

Triple shute screenA slotted opening wire mesh with three shute wires in adjacent crimps followed by the slot and repeated.

U-channelLongitudinal structural girders in the framework of each deck of a screen box. Also crown bar.

Vibrating screensA vibrating screen box is supported on springs, and is vibrated by a vibrating mechanism called an exciter, vibrating the screen box in various ways (circular, linear, and elliptic motions).

Warp The wires running length-wise during weaving are referred to as WARP wires.

Wedge boltA slotted bolt, a washer and a curved wedge that requires a hammer to tension or remove the screen mesh installed from the outside of the walls of a screen box.

Weft The wires that run across the width of the cloth are referred to as weft or shute wires.

Welded angle A fabricated hook welded on the tensioning edge of a flat screen panel.

Wire Metal that has been drawn out into a strand or rod.

Wire diameter The diameter of wire before weaving.

Woven wire cloth A general term for material woven from metallic wires. Also wire screen.
