Energy Saving Ball Mill
Spiral Chute

Spiral Chute

[Introduction]: A gravity separation equipment of separating minerals with different weight by the inertial centrifugal force generated in the spiral motion of pulp.

[Capacity]: 0.15~16t/h

[Improvement]: It uses high-quality, wear-resistant engineering plastics with properties such as acid and alkali resistance, flame retardancy, cold resistance (down to minus 30°C), UV protection, and aging resistance. Its service life is longer than that of fiberglass.

ADVANTAGES

PRODUCT STRUCTURE

The main components include the supporting device, material distribution trough, upper hopper, spiral blades, and discharge hopper.The slurry spirals downward from the top, and the ore is separated from the sand under the action of gravity component and inertial centrifugal force.


Based on the differences in specific gravity, particle size, and shape between useful minerals and gangue minerals, slurry dynamic centrifugal flow film can generateon the spiral inclined surface. Inthe combined force field of gravityand centrifugal forces, separation of useful minerals from gangue minerals can be achieved by leveraging the varying forces acting on different particles, including gravity, hydrodynamic pressure, and friction.
