Spiral separator is one of mineral processing equipments. It is a kind of mechanical 

grading device by taking advantage of the principle that solid particles with different 

gravity have different precipitation speed in the liquid. Spiral classifier is capable of 

classifying and filtering materials from the grinding mill and then sending the coarse 

materials back into the mill by spiral blade and discharging the fine materials from the 

overflow tube. There are mainly four types of spiral classifiers: high weir single spiral 

classifier, high weir double spiral classifier, immersed single spiral classifier and 

immersed double spiral classifier. Spiral separator: http://www.ms-

Application of Spiral Classifier: This series of spiral classifiers are suitable for 

dewatering, medium draining, desliming and wet and dry classifying of minerals and non-

metal materials. Belt Conveyor: http://www.ms-machinery.com/product/belt-conveyor.html
Working Principle of Spiral Classifier: Spiral classifier makes use of the principle that 

solid particles with different sizes and specific gravity have different precipitation 

speed in the liquid. Fine mineral particles float in the water and flow out, and the 

coarse ore particles sink into the bottom. The pedestal of spiral classifier is made of 

U-steel. Its body is welded and made of steel plate. Spiral shaft is coated with pig iron, 

which makes it wear resistant and durable. Spiral classifier has two types of lifting 

devices, electric lifting device and manual lifting device. Email Adress:info@ms-
