Spiral classifiers

Spiral classifiers are applicable for wet classification of ferrous, non-ferrous metal ores and other similar materials by size and density as well as for desliming sands and dewatering slurries.

Features

- Simple in design;
- Reliable in operation;
- Smooth agitating action of the spiral;
- As distinct from rake classifiers operation can be stopped with tank filled with slurry.

Application

- Processing plant laboratories for operation in closed circuit with mills to yield 0,83 - 0,15 mm solids in overflow
- Cleaning of building sands at the dredging site.
