Spiral classifier is a mechanical classification machine based on the principle that the specific gravity of solid particles is different in the speed of precipitation in liquid. During the beneficiation process, the ore needs to be ground to a certain fineness so that the fine-grained useful minerals and gangue can be fully dissociated and ...
The overflow of the low- spiral classifier is often lower than the center of the bearing at the overflow end, so the area of the settlement area is too small.
