Embodiment
Illustrated embodiment below in conjunction with the accompanying drawings, the invention will be further described.
Ore pile（2）It is arranged on before semi-autogenous mill, is for storing ore, and adjusting broken produced with grinding operation
The equipment breakdown of system and the difference of working system.Ore is broken by gyratory crusher, under fall on ore pile（2）During meeting
" segregation " effect is produced, the rule of segregation effect is：The bigger ore of particle is more walked toward both sides in dropping process, and particle is smaller
Ore is in center.The premise for producing segregation effect is that ore pile is necessary for " pyramid ", and the heap-type of ore pile is pyramid
When it is as shown in Figure 1.If " recessed " type is presented in ore pile, segregation effect is lost, when the heap-type of ore pile is matrix such as Fig. 2 institutes
Show.If therefore by above-mentioned phenomenon on the premise of semi-autogenous mill ore grinding requirement is met, holding ore pile " pyramid " type will be right
The proportioning with ore deposit especially size block of grinding machine has vital influence, if ore pile is presented " recessed " type and will lost with ore deposit
Effect.
This method is realized by technology hybrid programmings such as .NET technologies, database technology, sensor technology, matlab technologies
To the final semi-autogenous mill grinding efficiency for realizing raising grinding machine of " pyramid " type control of ore pile.Ore pile（2）Material position letter
Number, pass through radar level gauge（1）By signal acquisition, passed to by DCS and OPC communications in database, by .NET technologies,
Matlab technologies, database technique provide weight plate batcher below ore pile to the intellectual analysis of level signals（3）Tune
Section instruction includes（Open and frequency regulation）, finally realize " pyramid " control of ore pile.

Allowed band, realize the mine-supplying quantity of stable grinding machine, and then change the frequency of different heavy plate batchers.
Weight plate batcher boot sequence Controlling principle is determined secondary.To ore pile, it is desirable to the turnover balance of ore, it is not only
Turnover balance in ore deposit amount, includes the turnover balance of various sizes of ore.Require that the shape of ore pile keeps " golden word simultaneously
Tower " type, is easy to carry out the classification that ore deposit ore forms size block under segregation effect.Therefore, 12 weight plate batchers are according to ore grinding block
Degree control program starts in a certain order, it is to avoid certain weight plate batcher occurs and does not work and the phenomenon of heap ore deposit for a long time,
And according to the level signals above weight plate batcher, when there is matrix in the shape of ore pile, the startup of regulation weight plate batcher
Sequentially, it is to avoid matrix is continuously formed.
Finally, after control suggestion is provided, system can enter line frequency adjustment according to the heavy plate batcher situation currently opened.When
When output result is increase lump ore ratio, the heavy plate feed unit frequency increase of relatively large ore, while to ensure overall ore deposit
Amount is constant, and the frequency of fritter ore weight plate batcher can reduce corresponding frequencies；When output result is reduces lump ore ratio,
The heavy plate feed unit frequency of relatively large ore reduces, the heavy plate feed unit frequency increase of fritter ore；When output result is uncomfortable
During whole ore ratio, the frequency for opening weight plate batcher is constant.
