Spiral Classifier Product features

They are widely used to separate ore sands by forming a closed-circuit with the ball mill in concentrators, or gravity concentrators to classify ores and fine muds.

Low maintenance cost

The spiral classifier needs to be soaked in the pulp for a long time, so it is easy to wear. Our company adopts thickened wear-resistant plates, which can reduce wear, prolong service life and reduce maintenance costs.

Stable operation

The spiral classifier has a high degree of automation, convenient operation, safety and reliability, and adopts frequency conversion control technology, which ensures stable operation, and its simple structure makes it easy to replace spare parts.

High processing efficiency

The spiral classifier is often combined with the ball mill and other beneficiation equipment to form a closed-circuit or open-circuit system, with a maximum output of 400tph, suitable for use in large and medium-sized beneficiation production lines.

Energy Saving

The spiral classifier improves the beneficiation efficiency, and the washed sewage can be recycled and used in other places to achieve the purpose of water saving.

Working principle

What Is The Working Principle Of The Spiral Classifier

The spiral classifier is mainly composed of a motor, a spiral blade, a spiral shaft, a tank body, a lifting mechanism, and a high wear-resistant liner.

The spiral classifier filters according to the gravity and falling speed of different particles. The fine particles floating in the water will be discharged from the upper part, and the coarse particles will sink to the bottom of the tank, and then the spiral blades will rotate the coarse particles to the feeding part to continue processing until reaching the ideal granularity.
