Classifier Applied in Ore Beneficiation

Ore beneficiation production plant is mainly made of jaw crusher, ball mill, classifier, magnetic separator, flotation machine, thickener and drier, with feeder, lifter and conveyor as supplements.

The procedure of the production line goes like this: the ore is first sent to jaw crusher for primary crushing. Then the ore with a proper size for secondary crushing will be sent into the ball mill for fine crushing and grinding. The ore powder discharged from the ball mill will be sent to the next procedure: classifying. Because of the different sedimentation rate due to the varied specific gravity, spiral classifier can clean and group the ore mixture. The cleaned and grouped mixture is sent to magnetic separator, due to the different susceptibility, magnetic substance can be separated from the mixture under magnetic and mechanical force. Then the mixture is sent to flotation machine, according to the features of different ores, we can add different additive into the mixture to separate the ore we want from the mixture. 'After the separation from the mixture, the ore we want always contains a lot of water, we need a thickener to have it concentrated first and then dried by a drier; eventually we can get dry ore.

We can know that it is important for magnetic separator and flotation machine in ore separating line .so installing and application is necessary for them. as follows :

The Magnetic Separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force.

Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design, which has a proven record of high efficiency. sand maker:http://www.crusher-machine.com/18.html

Magnetic speartor: The Magnetic Separators are available in cyclic design with process vessel diameters smaller than 3mm. Wet Magnetic Separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephline. Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix.

Flotation machine: When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until becomes residue

This production plant enjoys the advantages of high efficiency, low energy cost, high production capacity and economy and rationality.
