Application Areas

Iron Ore Separation
Gold Ore Separation
Tungsten Ore Separation
Tantalum Ore Separation

Work Principle

The ore propeller rotates and flows from top to bottom from the two feed ports of the spiral chute. Ore and sand are separated under the action of gravity and centrifugal force due to differences in specific gravity, particle size and shape. The concentrate flows into the concentrate hopper and the tailings flows into the tailings hopper.
