introduction of Spiral Classifier:

Spiral Grader has 4 types, high-dam single spiral, high-dam double spiral, submerged single spiral and submerged double spiral.
It is widely used in beneficiation plants for classifying mineral sand with ball mill to form closed cycle, in gravity beneficiation plant for classifying mineral sand and fine mud, in the process of metal beneficiation for granularity classifying of ore magma and ore washing process for desliming and dewatering.
It can filter the granularities from the machine and then spin the rough particles to charging part by spiral vane and discharge the fine granularities from the overflow pipe. The base of the machine adopts a channel steel and the body adopts welded steel plate. The water inlet of spiral axle and axle head adopt pig iron cover for wear proofing and long life operation. The lifting equipment has two types, manual control and electric control.

Main benefits of Spiral classifiers:
1/ Energy saving, 2/ Heavy duty, rugged construction, 3/ Powerful self-contained spiral lifting devic, 4/ Continuous spiral raking, 5/ Optimal particle size range 800 to 75 microns.

Spiral Classifiers are suitable for:
Separation of fine particles and liquid from coarse particles, light particles from heavy particles, particles into a number of products graded according to size, liquid from solid particles.
