Product introduction

Spiral classifier is widely used in mineral processing and forms one closed circulation with grinding equipment

It is applied for the per-classification, fine-grained mineral mud off, dehydration, washing, grading and so on. It can efficiently control mineral particle size, improve the grinding efficiency and reduce the over-crusher

The overflow spiral blade is higher than overflow level, and the overflow spiral center is lower than overflow surface. The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm.

Product Advantages

1, Used in mechanism of dry sand production process---the separation of the stone exceeds bid, can be convenient to control sand powder content, to meet the requirements of the customers.

2, Suitable for dry big, medium-sized system use sand production line.

3, 0.00-0.75 mm in cement content between 2% and 15% can be adjusted.

4, Easy to control the quality of stone, fineness, flexible, convenient adjustment and reliable.

5, Tile lining, maintenance rate is very low.

6, USES frequency conversion control technology, operating more concise.

operating principle

The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.
