Classification and Application Scope

The screw classifier is also called spiral classifier. There are mainly four types of classifiers, namely high weir single spiral classifier, high-weir dual spiral classifier, sinking single spiral classifier and sinking dual spiral classifier.

The classifier can form a closed circuit with the ball mill for distributing the ores, grading the ores and fine mud in the gravity mills, grading slurry in the metal ore dressing procedure or for desliming and dehydrating in ore dressing process.

Features

1. Simple structure

2. Reliable operation

3. Convenient maintenance

4. Low cost

5. High efficiency

Working Principle

According to the principle that different particle sizes with different proportion have certain terminal velocity, the fine particles float on the water and overflow out while the coarse particles sink to the bottom and then they will be pushed upward and discharged. The powders will be filtered, with the substandard particles screwed into the feeding port by the spiral vanes and the fine ones discharged from the overflow pipe. The head of the screw axis and the shaft adopt the pig iron cover, which is wear-resisting and durable. There are manual and electric lifting devices separately.

The Structure

The classifier is composed of the transmission device, the spiral, the trough, the lifting mechanism, and the lower bearings (bush) and the discharge valve.
