Description
Technical field
A kind of ore pulp grading plant relates to the pre-classification of mineral and the device of controlling classification in a kind of mineral fine grinding/process of regrinding.
Background technology
Along with the poor hydridization of mineral resources, ore more and more needs to regrind/and fine grinding to be to realize the monomer dissociation of mineral, satisfies the requirement of flotation.Yet the overground argillization that then may cause ore can worsen follow-up flotation environment again.Therefore, for regrind/the fine grinding mineral products need discharge and carry out classification fast and handle.Mineral Classification adopts cyclone to finish usually, and regrind/fine grinding is because the process conditions requirement, output is general bigger, this just gives follow-up cyclone for coming very big branch stage load, cause cyclone classification inefficiency and energy waste, and because the cyclone sand setting can not in time return grinding machine and regrind, also caused the decline of grinding machine grinding efficiency.Thereby, need the big and advantages of simplicity and high efficiency equipment of a kind for the treatment of capacity to be positioned over to regrind/fine grinding equipment between cyclone, realize pre-classification and the circulation of mineral.
Classification is one of important operation of mineral processing.Present classifying equipoment mainly contains 4 big classes, i.e. hydraulic classiciation, air current classifying, sieve classification and compound force field classification etc.According to the difference of active force, be divided into two kinds of gravity classification and centrifugal force classifications again.Main and the grinding machine formation closed circuit grinding of mechanical classifier plays pre-classification and control grading.The regrinding of ore pulp/fine grinding product generally need carry out classification through cyclone, and goes to toward being mounted with the pre-classification device in classification, adopts circular cone hydraulic classifier or cone classifier (branch bucket) or other similar grading plants usually.
The circular cone hydraulic classifier is that a kind of power of relying on for support, waterpower realize the equipment by the particle sinking speed classification.Wherein the base cone hydraulic classifier is the most famous recklessly with Finland, and it is applicable to the classification of fine.Its principle is that rotating shaft drives distribution plate and mozzle is done to rotate slowly, and deflection cone and stirring vane are equipped with in the rotating shaft lower end.Radial plate is housed around the mine feeding tube, produces rotation in order to prevent the top ore pulp.Ore pulp feeds from mine feeding tube, and under the distribution plate effect, particle is thrown to place, peripheral slit, and wherein sinking speed is taken away by upwelling less than the particle of upwelling speed, discharges from top, becomes the particulate overflow.Sinking speed is then slowly falling in the rotary course greater than the particle of upwelling speed, when when adding water and feed the district, is subjected to the effect of ascending current, and the fine grained that wherein is mingled with is taken away by ascending current, is back to the mining area through mozzle and distribution plate.The coarse granule that continues to fall is discharged from spigot and is become the heavy ore deposit of coarse grain.
Dividing bucket is a kind of cone classifier simple in structure, and its profile is a circular cone that stands upside down, and is provided with mine feeding tube at the liquid level center, and the cylinder bottom is in the following certain depth of liquid level.Ore pulp tangentially feeds center drum, is flowed out by the bottom after cushioning.The ore pulp that flows out is radial and goes to the peripheral overflow weir flow.In this process, sinking speed just sinks in the groove greater than the coarse granule of rising component velocity, and discharges through the bottom spigot.Particulate enters overflow launder with the top layer ore pulp, discharges as overflow.
Because circular cone hydraulic classifier ore pulp is fed by the middle part, need the power input that ore pulp is disperseed, fine-graded mineral reclaim needs external water source to feed.Its complex structure, consumed energy and production capacity are little.Divide bucket then be ore pulp tangentially feed the middle part give the ore deposit cylinder because the cylinder volume is less, the ore pulp that tangentially feeds can't form bigger centrifugal rotatablely moving, and has only played the effect of even dispersion ore pulp.Simultaneously, dividing bucket also to need to feed external water source just can impel thickness grain mineral to separate.Though its structure is simple, but does not need the power classification efficiency low, the configuration discrepancy in elevation is bigger.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provide a kind of simple in structure, power consumption is low, the efficiency of separation is high, be particularly suitable for mineral regrind/the fine grinding loop in pre-classification between grinding machine and cyclone and the ore pulp grading plant of control classification.
