In mining, sand production and mineral processing operations, uniform particle size, effective desliming and dewatering are critical to production efficiency and final product quality. With a mature and stable structure, the spiral classifier has long been a reliable and widely used classification equipment in the industry.
It classifies materials based on the difference in settling velocity of solid particles in slurry. Coarse particles settle at the bottom and are pushed back for re-grinding by the spiral, while fine materials flow out with the overflow, completing particle size separation, desliming and dewatering. It is often used in a closed circuit with ball mills to ensure smooth coordination between grinding and classification.
The spiral classifier features simple structure, low failure rate and easy operation & maintenance. It runs stably with moderate energy consumption, suitable for continuous production. The trough body and spiral blades are made of wear-resistant materials, ensuring a long service life even under harsh working conditions with abrasive ores and aggregates.
It is available in single spiral, double spiral, high-weir type and submerged type, which can be flexibly selected according to processing capacity and target particle size. It is widely applied in the classification of metallic ores, non-metallic ores, as well as sand washing and desliming, showing strong adaptability and practicality.
Focused on real performance and reliable quality, the spiral classifier effectively solves classification problems with mature technology, stable operation and low operating cost, making it a practical choice to improve production efficiency and ensure consistent product quality.
