Spiral Classifier
Spiral classifier is widely used in the concentrator with ball mill to create a closed loop process of triage process ore sand, in grading ore and fine clay in the gravity concentrator, in grading the particle size of pulp in metal beneficiation process and in demud and dehydration operations in ore washing work. With a simple structure, the screw classifier is reliable and easy to operate.
The screw classifier or sand classifier is mainly composed of transmission classification, spirochetes, tank, the lifting mechanism, the lower bearing (bush) and a discharge valve.
Fote is a well-known spiral classifier machine manufacturer in China. The product has high quality and guaranteed service. What's more, the screw classifier price is quite reseaonable.
