Ore Spiral Classifier of The Red Star
We Red Star mining machinery produce the ore spiral classifier which is famous at home and abroad. Let me briefly introduce it to you.

ore spiral classifier is used for processing minerals. It is often applied in quarries as beneficiation equipment. Based on years' experience of production, Zenith spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements.
Introduction
Spiral classifier, also called screw classifier, is widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and de-sliming and dehydrating in the washing.
According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe.
Application
When spiral classifier processing minerals, it is applicable for:
1.Separation of fine granularity and liquids from coarse particles
2.Separation of light particles from heavy ones
3.Grading the final products according to the particle size
4.Separation of liquids from solid particles
Working Principle
When spiral classifier processing minerals, it works based on the theory that different solid particles have different gravity and thus have different dropping speed. Fine particles floating in the water will overflow and the big ones will sink to the bottom and discharge from the upper part by spiral pushing. The base of the machine adopts a channel steel and the body adopts welded steel plate. The water inlet and head of spiral axle adopt the steel cover for wear proofing and long-term operation.
