Spiral classifier

Simple structure, Reliable running

Spiral classifier is beneficiation equipment. Because of the principle that solid particles with different specific gravity will get different deposition rate in liquid, spiral classifier can realize mechanical classification effectively.

Applications: Widely used in combine with ball grinder into closed circulation for ore-sand separation in the ore separation plant; classify ore sand and fine sludge in gravity ore separation plant.

Spiral classifier Details

1. Simple structure, reliable running and easy operation.

2. It mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity.2.
