Spiral Classifier also can be called spiral separator, screw classifier or screw separator. It is widely used in the concentrator and make up a closed-loop with ball mill.

With the development of industry, the successfulusage of modern machinery in industry, for economic development to make anoutstanding contribution. Coal mining technology is widely used, coalproduction continues to increase, and the coal in the end of the coal contentand the top and bottom of the mixed amount of the corresponding increase, whichto the coal preparation plant process design, production management andproduction cost management is very difficult, slime processing link processingcosts also increased. The successful application of spiral classifier in coalpreparation plant is a good combination of the characteristics of coal quality,thus reducing the difficulty of coal preparation plant management, but alsoreduce the processing costs and enhance the economic efficiency of enterprises.Therefore, the screw separator in the coal preparation plant application,compared to the traditional process, the advantage is more obvious.
Advantages are:
1. Low processing costs, no power, lowenergy consumption;
2. Through the spiral classifier of coarseslime products can be used coal slime centrifuge, sedimentation centrifuge andother dehydration equipment alone recovery, and high filter press recoveryprocess;
3. Sorting density greater than 1.6 kg / Lor more, you can achieve the desired sorting effect for most of the thermalcoal and optional coking coal sorting;
4. Compared with other coarse slimeclassifier equipment, its technology and equipment are more mature;
5. In view of the usage of large diameterheavy medium cyclone technology, although the increase in the processingcapacity of a single device, but the following 1 millimeters coal, the effectof mud sorting is obviously worse, even by increasing the feeding pressure andother means can improve the classifier effect, but also bring the systeminstability, slime immersion time is long, high energy consumption and manyother drawbacks;
6. Select a wide range of sizes, the upperlimit of 3 mm, and the lower limit of up to 0.15 mm or less.
Spiral classifier is a kind of separationequipment which can realize the separation of minerals with different densityunder the action of gravity and centrifugal force. That is, the material isbent around the vertical axis into a spiral chute, the usage of centrifugalforce and gravity of the sorting of the machinery. In the field of coalpreparation, mineral processing, spiral classifier has a wide range ofapplications.
