spiral classifier application

Spiral classifier is widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and desliming and dehydrating in the washing. Featuring simple structure and reliable operation, the spiral classifier is very popular with users worldwide.

spiral classifier structure

Based on the principle that different solid particles with different size and specific gravity have different dropping speed in the water, fine mineral particles floating in the water will flow out from the overflow pipe and the large ones will sink to the bottom and then be discharged from the upper part by spiral pushing force. The base of the spiral classifier is made of channel steel and the body is created with welded steel plate. The water inlet of spiral axle and axle head adopt pig iron cover for wear resistance and long life.
