Bruno user interface 1

• After successfully entered license an empty Bruno documentopens

• Bruno user interface consists of four windows

- Flowsheet (documents open on the flowsheet)

- Fraction curve - Result list

- Warnings




Bruno user interface 2

• Active window is selected with corresponding button in thetoolbar

• Warning window opens only after calculation

Bruno devices (from the left)

- feed

- feeder- primary and secondary gyratories

and cone crushers

- jaw crusher

- fine gyratories and cones

- horizontal shaft impactor

- vertical shaft impactor

- my crusher

- screen- silo and node

- product pile

- stock pile

- stock feed

- add text

- add picture




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





• 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





• 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





• General interleaf is forentering Plants name andother info about theprocess

• The information appearson the flowsheet belowMetso’s logo in the Plantand Info fields






Bruno devises - machine dialog

• Machine selectionand settings

- type

- model

- machine specific

settings

• Nominal operatingparameter limits areshown in the datafield on the right




Bruno devises - machine dialog

• Calculation can befine tuned with userdefinable factors oninterleaves

• Help on eachinterleaf providesdetailed informationabout the effect ofthe factors




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




Bruno devises - crushers

• Crushers main function isto reduce feed materialparticle size

• Crushers’ performancedepend on the type andsize

• Double click the symbol toopen machine dialog




Bruno devises - others

• There are some other processdevises available in Bruno

- product pile

- stock pile

- stock feed

- node/silo- My Crusher






Opening document

• Every time you start Bruno an empty document opens first• You can open existing document instead

- Click Open in the toolbar

- Select the document (.brn) in normal file explorer window




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




Device settings

• Double click each deviseto open the dialog andmake settings




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




Results on the flowsheet

- Material flows- screen efficiency

- F80/P80 crushing

ratio- crusher load

- product percentagesof the feed




Practice 1, Draw Bruno Flowsheet

• Select equipment

• Connect equipment

• Layout

• Right-angles inconnections

Modifying flowsheet

• Select Options menu anddisplay options to modifyflowsheet




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 .










Help

• Bruno’s help is divided into generalsection and machine section

• To open the general section click helpbutton in the toolbar

• Machine helps are opened by clicking

help button in a machine dialog




General help

• The general help is designed to give information about thewhole program and the features common for all the devises




Machine help

• The machine help contains instructions on problems withusing Bruno; for example entering parameters.

• Example: How does My factor for capacity effect?

Click help




Machine help




Machine help

• Help sections are linked together• More detailed information about calculation and other model

characteristics are described in general help




Getting help

• If problems occur that can not be solved with the instructionsin Bruno’s help, contact Bruno administrators.

[email protected]

• Describe:

- What did you want to do?

- How did you try to do it?

- What happened?




Exercise 2, Two stage crushing plant

• Please make Bruno simulation for the following crushingplant need:

- Feed material: hard gneiss, Crushability 28 %abrasion index 0.7 (1400 g/ton)

- Feed size: 0-600 mm medium

- Capacity: 200 tph

- Products sizes: 0-5, 5-20 and 20-40 mm
