.Features and technology advantages
1. Stable, easy control, wide range of concentration
2. Large capacity, high enrichment ratio, high recovery rate
3. Small cover space, less water consumption, simple structure, no need of power
4. Simple installation, convenient operation, less investment, quick return
Working principle
Ore pulps are uniformly fed into machine and form different layers as they pass across chute. Heavy minerals precipitate to bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner due to the speedy rotation. As a result, mineral particles with different density are divided into three zones as concentrate, middling and tailings.
