Specific embodiment
Illustrated embodiment with reference to the accompanying drawing, the invention will be further described.
Ore pile 2 is arranged before semi-autogenous mill, for storing ore, and adjusts broken and grinding operation production system
Equipment breakdown and working system difference.Ore is broken by gyratory crusher, under fall on ore pile 2 during can generate
The rule of " segregation " effect, segregation effect is: the bigger ore of particle is more walked toward both sides in dropping process, the smaller ore of particle
In center.The premise for generating segregation effect is that ore pile is necessary for " pyramid ", when the heap-type of ore pile is pyramid such as
Shown in Fig. 2.If " recessed " type is presented in ore pile, segregation effect is lost, it is as shown in Figure 1 when the heap-type of ore pile is concave.
If ore pile " pyramid " type is kept, by opposite grinding therefore through above-mentioned phenomenon under the premise of meeting semi-autogenous mill ore grinding requirement
The proportion of the ore matching of machine especially size block has vital influence, if ore pile is presented " recessed " type and will lose ore matching work
With.
This method is realized by technologies hybrid programmings such as .NET technology, database technology, sensor technology, matlab technologies
It is final to " pyramid " the type control of ore pile to realize the semi-autogenous mill grinding efficiency for improving grinding machine.The level signals of ore pile 2,
By radar level gauge 1 by signal acquisition, is passed in database by DCS and OPC communication, pass through .NET technology, matlab skill
Art, database technique to the intellectual analysis of level signals provide weight plate batcher 3 below ore pile regulating command (including
Open and frequency adjusted), final " pyramid " control for realizing ore pile.
Firstly, ensuring that grinding machine under the premise of guaranteeing semi-autogenous mill grinding efficiency, guarantees " gold using the means of fuzzy control
Word tower " type.The material position highest of 5#, 7# i.e. in level-sensing device 1, the material position time of 3#, 9# are high in level-sensing device 1,1#, 11# in level-sensing device 1
Material position is minimum.When 5# material position=3# material position in level-sensing device 1, illustrate that spill occurs in 5# material position in level-sensing device 1, if weight plate is given
7# weight plate batcher does not work in material machine 3, then suggests opening 7# weight plate batcher in weight plate batcher 3；If weight plate batcher 3
Middle 7# weight plate batcher has worked, then suggests closing 5# weight plate batcher in weight plate batcher 3, increase 7# in weight plate batcher 3
The output frequency of weight plate batcher.Since weight plate batcher is typically all to open in pairs, 6#, 8# weight in weight plate batcher 3
The control method of plate batcher is consistent with 5#, 7# weight plate batcher in weight plate batcher 3.It will weight plate along the central axes of ore pile
It is divided into two groups of 1#, 3#, 5#, 7#, 9#, 11# and 2#, 4#, 6#, 8#, 10#, 12# combinations in batcher 3, every group of control rule is all
It is consistent.It is the working time for counting weight plate batcher, too long when the working time for finding certain group weight plate batcher, then suggest switching
Its symmetrical weight plate.It is too short when the working time for finding certain group weight plate batcher, then suggest starting group weight plate.When ore pile
After carrying out nugget degree and having detection, then require being substantially the same for nugget degree and ore removal lumpiness.Live live effect figure, as shown in Figure 4.
Secondly, determining that ore fragmentation adjusts principle.It is inferred in grinding machine according to the variation of axis pressure, power, mill sound, hard rock amount
The variation tendency of portion's material position reduces bulk ratio when material position is high；When material position is low, increase bulk ratio.In combination with grinding machine
Feed preparation unit size composition, finally make material position stablize in suitable height.So that it is determined that the size block amount of feeding, and combine at flotation
The allowed band of reason amount realizes the mine-supplying quantity for stablizing grinding machine, and then changes the frequency of different heavy plate batchers.
Weight plate batcher boot sequence Controlling principle is determined again.To ore pile, it is desirable that the disengaging of ore balances, and is not only
Disengaging balance in mine amount further includes the disengaging balance of various sizes of ore.The shape of ore pile is required to keep " golden word simultaneously
Tower " type is convenient for carrying out the classification that mine 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, avoid the occurrence of certain weight plate batcher do not work for a long time and the phenomenon that heap mine,
And according to the level signals above weight plate batcher, when concave occurs in the shape of ore pile, the starting of weight plate batcher is adjusted
Sequentially, concave is avoided to continuously form.
Finally, control suggests after providing that system can be according to the heavy plate batcher situation making frequency adjustment currently opened.When
Exporting result is when increasing lump ore ratio, and the heavy plate feed unit frequency of relatively large ore increases, while to guarantee overall mine
Measure it is constant, fritter ore weight plate batcher frequency can reduce corresponding frequencies；When exporting result is to reduce lump ore ratio,
The heavy plate feed unit frequency of relatively large ore reduces, and the heavy plate feed unit frequency of fritter ore increases；When output result is uncomfortable
When whole ore ratio, the frequency for opening weight plate batcher is constant.
