Product Description
The mill and classifier are a correlated set. The effect of classifier has impact on the efficiency of mill. So it is a key point in the mineral separation process to select well the classifying equipment. The spiral classifier can be divided into the single spiral classifier and double spiral classifier according to the spiral axle quantity.
Spiral Classifiers are suitable for:
1. Separation of fine particles and liquid from coarse particles
2. Separation of light particles from heavy particles
3. Separation of the particles into a number of products graded according to size
4. Separation of liquid from solid particles
principle:
The classifier is grading equipment, according to the principle that solid particles size and proportion are different, thus the settling velocity in liquids is different, fine mineral particles floating in the water to overflow out, the crude ore particles settling to the bottom, then discharged by the spiral into the upper part, to carry out grading.
It is able to grade and filter the material which grinds to powder by grinding mill, then use of helix vane, send the coarse material into mill feed mouth, and filter out the fine material discharged from the overflow pipe
Features:
1. Energy saving
2. Heavy duty, rugged construction
3. Powerful self-contained spiral lifting device
4. Continuous spiral raking
5. Optional automatic lubrication system;
6. Wide choice of tank design
