Spiral Classifiers

Spiral classifiers are commonly used in mineral processing to control the grinding particle size in closed circuit processes with ball mills, or to grade ore and fine slimes in gravity concentrators, as well as for desliming and dewatering in ore washing operations. The machine has the characteristics of simple structure, reliable operation and convenient operation. Elevate

Product Overview

Working principle

The spiral classifier works by utilizing the principle that the size and specific gravity of solid particles vary, resulting in different settling velocities in liquids. Fine particles float in the water and overflow, while coarse particles sink to the bottom of the tank. A classification device that mechanically grades materials by pushing the material upwards through a spiral to discharge it. It can filter the material powder produced by grinding in the mill, and then use the spiral to rotate the coarse material into the mill feed port, and discharge the filtered fine material through the overflow tube. The machine base is made of channel steel and the body is welded from steel plates. The water inlet and shaft head of the screw shaft are made of cast iron sleeves, which are wear-resistant and durable. The lifting device is divided into two types: electric and manual.
