Description

Ore beneficiation production line is mainly composed of jaw crusher, ball mill, classifier, magnetic separator, flotation machine, thickener and drier, with feeder, lifter and conveyor as supplements. This production line enjoys the advantages of high efficiency, low energy cost, high production capacity and economy and rationality. 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 gouped 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.
