High efficiency spiral sand classifier with low price
Spiral sand classifier Application:
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. This product features simple structure, reliable working conditions and convenient operation.
Spiral sand classifier working principle:
The classifier use the principle that different grains have different specific gravity and sedimentation rates in liquid, the fine ore to flow in the water, while coarse ore sinks to the bottom.This classifier can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically.
Spiral sand classifier Feature:
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
