Specification of Spiral Grader:
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 has the features of simple structure,
reliable operation, and convenient operation. The
working principle of the grader is that different solid granularities
have different gravity and thus have different dropping speed. The
fine ore granularities floating in the water will overflow and the big
ones will sink to the bottom and discharge from the upper part by
spiral pushing. 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.
