Product Description

Double screw spiral classifier machine for mineral ore separating

Spiral classifier introduction

Classifier is one of the important equipment in ore dressing process, and the most commonly used type is spiral classifier, which is also called screw classifier. Spiral classifier carries out mechanical grading by using the principle that different proportion of solid particles have different precipitation rate. 

Spiral classifier has four types: high weir single-spiral classifier, high weir double-spiral classifier, immersed type single-spiral classifier and immersed type double-spiral classifier.

Spiral classifier working principle

Spiral classifier is mainly composed of transmission system, spiral part, chute, lifting part, upper support and ore discharging valve. It is a type of classifying machine that classifies materials based the principle that the solid particles with different sizes and proportions have different falling speed in the liquid, and fine ore particles float in the water and coarse ore particles sink to the bottom of the chute and the coarse ore particles are pushed by the spiral to the upper part and discharged. This machine is able to filter the powdery particle crushed by the grinding mill and whirl the coarse particles with the spiral to the feeding mouth of the grinding mill and discharge the filtered fine particles.

Spiral classifier main features

1.Simple structure, reliable running and easy operation.

2. It mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity.

3. It can classify the ground material powder from the grinder, spiral the coarse grain into material inlet of grinder through the spiral chip, and discharge the classified fine grain from overflow surface.

4. Its base is made from channel steel, and its body is welded from steel plate.

5. The lower support of spiral bearing is of engine-bearing structure of good wear-resistance and durability

6. The lifting device is of electric and manual mode.

Spiral classifier application

This spiral classifier is widely used to combine with the ball grinder in a closed circulation for ore-sand separation in the ore separation plant., classify ore sand and fine silt in the gravity separation plant, classify the granularity from the pulp in the metal ore beneficiation flow and remove the slime and water in the ore washing process.
