Through continuousdevelopment, HAVER’shorizontal impeller fil-ling machine is designedto pack highly flow-resi-stant, powder-type, loosematerials that are proneto clogging.

Features

• especially adaptable todifferent materials andmaterial flow characte-ristics

• large material inletcross section

• high filling speeds• continuous material

feeding (no clogging,no bridging)

• high filling speedswhile maintaining tightweight tolerances

The air entrainment machineaccording to the gross weight filling system is used for fillingfree flowing materials as well astechnically difficult powder-typeand granular products.The pressure chamber aerationconcept provides optimum productflow with minimal air consumpti-on. Aeration rates depend on the product characteristics and areindividually adjustable.Thanks to continuous suctionduring filling, high filling rateswith minimum internal bag pressure are assured.

HAVER system components

Various HAVER filling spout designs

Ring gap aeration

• reduces wall frictioninside the filling channel using minimalaeration, without airreaching the core of theproduct flow

• this leads to a clean fil-ling process under ahigh filling pressure thatyields a high densitypacking

• switching on and off theaeration as a function ofthe filling speed

Bag sensors

• for detecting the positi-on of the valve-bag onthe filling spout beforefilling begins

• for reliable, fully auto-matic operation

• sensors operating inde-pendently of each otheraccording to varioustechnical principlesassure maximum availa-bility of the HAVERpacking plants

Filling spout

• individual designs thatmatch specific equip-ment layouts, productrequirements and bagspecifications

Exact flow rate dosing andshort reaction times inchangeovers to coarse flowor to fine flow and closingthe filling channel requireespecially reliable compo-nents.

HAVER fulfils these requi-rements down to the detail:

• under the most extremeconditions, independentof the product type or filling system, pinch valves have proven themselves for complete-ly closing the fillingchannel

• special slide valves mini-mize wall frictionthrough their compactsize, and are available instandard or in wear-resistant designs

• depending on the materi-al type, the fine flowcross-section of the filling channel may beregulated manually, ormotorized with a three-position pneumatic cylinder

HAVER bag chair variants

Bag chairs for manual removal, manually height adjustable

For machines with the manualremoval of filled bag, the bag chairmay be adjusted to suit the lengthof the bag using just a few motionsof the hand.

Bag chairs for automatic, vertical bag discharge - manual-ly adjustable

When only one bag size is used orwhen bag changeovers are seldom,then the tip-chair for automaticdischarge may be height-adjustedusing standard tools.

The valve-bag, in itsvarious shape formatsand for different produc-ts, is a highly flexiblepackaging system thatallows loose, bulk mate-rials to be packed econo-mically. And due tosound valve-closing tech-nology and virtual elimi-nation of spillage, awhole new range ofapplications has resulted.

New techniques for airescape from bags nowallow practically airtightbags to be filled. Thebest filling system isdetermined by conside-ring the properties of theproduct to be filled, thedesign of the bag andespecially its air permea-bility characteristics.
