Spiral classifier is widely used in closed circuit ball mill for grading ore, sliting gravity plant, grading granularity, ore beneficiation and dewatering. There are two types of spiral classifier, single spiral classifier and double spiral classifier.
According to the spiral blade at the flooding end, there are two types: high weir type: the top side of spiral blade is higher than the flooding level. Low weir type: the center of blade is lower than the flooding level. High weir type is used for classification of the ore with flooding size between 0.083-0.15mm Low weir type is used for classification of the ore with flooding size between 0.15-0.07mm.
1. Can be very convenient to control the content of sand powder and to meet users' requirements.
2. Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line.
3. The content of powder with size of 0.00--0.75mm is between 2%-15% and can be adjusted.
4. The quality of powder is easy to control. The adjustment of fine is convenient, flexible, and reliable.
