Bruno devices - Feed
• Define:
- feed rate
- feed material
- feed gradation
• Double click on the symbol toopen Feed dialog

Bruno devises - Feed
• Feed Rate will begiven as t/h (or st/hif imperial units areselected)
• If Feed Rate has
been set 0, Brunocalculates the topcapacity of theprocess

Bruno devises - Feed
• Select material from the list• The default material is granite
• Select My material if you wantto define your own material
• Material data button opensMaterial data window, whereyou set material properties
• Click help if you want to knowdescription of the properties

Bruno devises - Feed
• Select feed gradation from thelist
• Feed gradations are definedby top particle size 200mm -2000mm
• There are three basicgradations for every size
- fine
- medium
- coarse
• To define own feed gradationselect MyFraction and clickInsert MyFraction button

Bruno devises - feeder and screen
• Feeders and screens typicallydivide material flow into 2 - 5fractions
• Pan feeders just transfermaterial without changinggradation
• Double click the symbol toopen machine dialog

Configuring a process
• add all the machines of the process on the flowsheet• define process flow
• set the machine settings
Rules:• there must be at least one feed and one product in every
process
• all the machine inputs and outputs must be connected

Adding machines 1
• Select a machine from the toolbar by clicking a button
• move cursor to the drawing area and it changes into a wire framepicture of the selected machine
• click right mouse button to drop the machine

Adding machines 2
• Machine symbols can be moved on the flowsheet• click right mouse button on a machine or near a machine and
the symbol colors become negative
• when cursor is on the black rectangle and right mouse buttonis pressed, the symbol can be moved.

Process flow
• After adding all the needed machines the process flow has tobe defined
• First select connection tool

Process flow 2
• Connect machines frommachine output to machineinput.
• Output is marked with asquare and input with a circle
• click on a square and movethe cursor onto circle and click

Calculate a process
• Click calculate in the toolbar• The calculation progress is
shown in the bottom left corner
• Bruno gives a warning if:
- all the flows are not connected
- flows are connected wrong
- some device settings are notset
- there is no feed and/or productin the process

Calculate a process
• Bruno gives warning also if the algorithm can not calculate aresult
• Typical warnings are
- Closed circuit does not converge = some material fraction cannot be removed from the loop causing continuously increasing
flow rate.- Too many loops finding top capacity = the maximum number of
iterations has been reached.
• Solution: some machine parameters have to be changed.

Results
• The calculation results are divided in three sections- warnings
- results on the flowsheet
- fraction curves
- result list

Warnings
• If needed warning window opens after calculation• Warnings give indication of exceeding nominal operating
parameters of the machines

Fraction curve
• Select process flow and open fraction curve window to seethe particle size distribution of the flow.
• To select more than one flow keep shift button pressed andselect as many flows as you need.
• Note! More than two curves in the same window makes the
diagram difficult to read. See for your self .
