Spiral Classifier

Spiral Classifiers are widely used in the distribution of ore in closed circuits with ball mill in mining processing, in order to get a certain degree fineness of ore particles, meanwhile increasing the efficiency of grinding. This machine can also be used to wash sand,classify ore sand and play other functions.
We produce high weir type, single and double spiral, and immersed single and double spiral classifiers.

Main features of spiral classifier for ore:

1. Adjustable weirs
2. Sealed, submerged bearing
3. Optional automatic lubrication system
4. Rigid tank and substructure
5. Wide choice of tank design
6. Overflow collection box
7. Wide range of industries serviced
8. Single spiral range from 300 mm to 2 200 mm
9. Duplex spiral models 1 500 mm and 2 200 mm
