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.
