Principle overview：
The pump will sent the ore sand in two inlet,by adding supplementary water, regulate the slurry concentration. The slurry swirls from top to bottom, produce an inertial centrifugal force. Because of the size, shape, proportion of ore sand, by the effects of gravity and centrifugal force, it will separate the ore and sand. The concentrate come into the concentrate hopper then storage . The sand come into the tailing hopper then discharged by the pump.
Selection instructions：
Glass steel spiral chute is an advanced high effect-ion gravity separation equipment. It works for particle size 0.3-0.02mm metal, such as Iron, tin, tungsten, tantalum, niobium , gold, coal, monazite, zircon and nonmetallic minerals.
Model Description：
1. High efficiency, high recovery, ore separation accuracy;
2. No need for power;
3. Light weight, rust proof, wear resistant, corrosion resistant;
4. Low operating costs, long service life;
5. Strong adaptability to ore yield, concentration, particle size and grade;
6. The friction of carborundum surface makes the dressing effect better than plastic surface.
