Spiral Classifier

Spiral classifier is one of the equipment for mineral processing. It is based on the principle of different density of solid particles and different settling speed in liquid. The grinding powder can be filtered and classified, then the coarse material can be rotated into the feed inlet of the mill by spiral slice, and the fine material filtered out from the overflow pipe.

Working 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.

Application

Spiral classifier has the characteristics of simple structure, reliable work and convenient operation.

1. Working with ball mill in mineral concentrating that form a closed circuit operation to distribute ore sand;

2. Classification of ore sand and fine mud in separation plant;

3. Granularity classification of slurry and desliming and dehydration in the process of metal dressing;

4. Operation of desliming , dewatering and other operations in ore washing operation.

 

Main Features

1. Low power consumption;

2. Heavy duty, long working life;

3. Powerful self-contained spiral lifting device;

4. Continuous spiral raking;

5. High classifying efficiency;

6. Wide choice of weir height;

7. Rigid tank and substructure;

8. Wide choice of tank design;

9. Wide range of industries serviced.
