Overview

This spiral classfiers suitable for dewatering, medium, drainaging amd spraying in ore clressing for medium and fine naterial wet and dry classifying in mine.
Such machine is mainly used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 14-325 meshes are classified. Waste mud or water for ore sand can be separated from the ores.

Structure Description of Spiral Classifier
1. General Description
This kind of machine is composed of transmission mechanism, (left, right) spiral water tank, lifting device, lower support, lubricating device, ore discharge valve, feed inlet, etc (See the attached general drawing for details).
The water tank of this machine is installed obliquely. The angle of inclination is determined according to equipment configuration of equipment in the process flow. The (left, right) spirals driven by the transmission mechanism rotates in the water tank. The finely grained slurry enters the water bank from the feed inlet at one side and forms one slurry precipitation zone, whose surface area and volume depends on the value of the water tank's inclination angle and the height of overflow edge. The spirals rotating at a low speed play a certain stirring role. After the slurry is stirred, the light and fine particles float above the surface and overflow from the overflow edge. Then they flow into the next working procedure of ore dressing. The heavy and thick particles sink into the bottom of the water tank and become return sand which is transported by the spirals to the ore discharge mouth for discharge.
