Spiral Classifier is widely used
Spiral classifiers are used for the classification of bulk materials in large-scale ore dressing plants and mineral processing.
- Classification in closed-circuit grinding processes
- Classification and dehydration of coarse-grained minerals
- Reducing solutions in wet ore dressing
What Is Spiral Classifier
Sandreck is a large-scale Spiral Classifier factory with global operations and is a professional processing equipment manufacturer and supplier. The Spiral Classifiers are widely used in closed-circuit grinding processes for the classification of metal or non-metallic minerals such as iron ore and tungsten ore, as well as coarse sand particle desludging and pulp particle size classification, especially in ore settling particle size and seed recovery.
Spiral Classifier Advantages

Based on the spiral rotating chute, the synergistic effect’s gravity and water on the separation efficiency of Spiral Classifier is maximized.

The wear of the spiral blades, shell and trough body is greatly reduced, and the spiral blades are lined with high manganese steel and wear-resistant plates.

Sandreck Spiral Classifier has a slotted design, so it is easy to discharge the equipment parts maintenance and make it less downtime.

The lifting mechanism can adjust the spiral height and flexibly adapt to the needs of slurries of different concentrations and different particle sizes.

The low-speed and high-torque transmission system runs smoothly, and the power consumption is 60%-70% of similar equipment.

As a large-scale equipment manufacturer. The spiral classifier is sold to customers at a standard price.
Why Choose Your Spiral Classifier?
Generally speaking, Sandreck is a Spiral Classifier source factory. The Sandreck Spiral Classifier consists of an inclined trough, a spiral blade and a transmission system. It has a motor-driven rotating spiral blade and a lifting mechanism that can be automatically adjusted according to the amount of returned sand. The steel structure bracket with a stable appearance supports the equipment to proceed steadily.
