high weir spiral classifier
1Application of spiral classifier:
1. Classifying mineral sand with ball mill to form closed cycle in beneficiation plants
2. Classifying mineral sand and fine mud in gravity beneficiation plant
3. Granularity classifying of ore magma, in the process of metal beneficiation
4. Ore washing process for desliming and dewatering

Spiral classifier Working principle:
Different solid granularities have different gravity and thus have different dropping speed. The fine ore granularities floating in the water will overflow and the big ones will sink to the bottom and discharge from the upper part by spiral pushing. It can filter the granularities from the machine and then spin the rough particles to charging part by spiral vane and discharge the fine granularities from the overflow pipe. The base of the machine adopts a channel steel and the body adopts welded steel plate. The water inlet of spiral axle and axle head adopt pig iron cover for wear proofing and long life operation. The lifting equipment has two types, manual control and electric control.

Main benefits of Spiral classifiers:
Energy saving
Powerful self-contained spiral lifting device
Continuous spiral raking
Optimal particle size range 800 to 75 microns
