Introduction

Spiral classifier is a mechanical classification machine based on the principle that the specific gravity of solid particles is different in the speed of precipitation in liquid. During the beneficiation process, the ore needs to be ground to a certain fineness so that the fine-grained useful minerals and gangue can be fully dissociated and separated to achieve separation. From the technical and economic point of view, the spiral classifier machine plays a very important role in the grinding operation. Spiral classifiers are widely used in dressing plants to form a closed-circuit cycle with ball mills to separate ore sands, or to classify ore sand and fine mud in gravity beneficiation plants, and to classify ore pulp in metal beneficiation processes, and to wash ore desliming, dehydration and other operations during operation.

Principle

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.
