Product Description

Spiral classifier is called classifier for short. It is one of the important mineral processing equipment. There are four main types: high weir single spiral classifier, double spiral classifier, submerged single spiral classifier and double spiral classifier. It is suitable for separating ore sand in a closed-loop process with a ball mill in a mineral processing plant, or for classifying ore sand and fine mud in a gravity mineral processing plant, and for particle size classification of ore pulp in the metal mineral processing process, as well as desludging and dehydration in mineral washing operations.

Working Principle

The spiral classifier is a grading device that uses the principle that solid particles of different sizes and specific gravities have different settling speeds in liquids. Fine ore particles float in the water and overflow, while coarse ore particles sink to the bottom of the tank. The material is pushed to the upper part by the spiral to be discharged for mechanical grading. It can filter the powder ground in the mill, and then use the spiral blades to rotate the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe. The base of the machine is made of channel steel, and the body is welded with steel plates. The water inlet and shaft head of the spiral shaft are made of cast iron sleeves, which are wear-resistant and durable. The lifting device is divided into electric and manual types.
