Classifier is one of the important machines in the ore beneficiation process and it is widely used to form a closed-cycle with ball mill in the ore dressing plant to separate the ore sand, or to classify the ore sand and slurry in the gravity separation plant, grade the particles of the ore pulp in metal ore beneficiation process and to remove the mud and water in ore washing process. The commonly used classifier is spiral separator.
Spiral classifier is mainly composed of transmission system, spiral part, chute, lifting part, upper support and ore discharging valve. This classifier has the advantages of simple structure, reliable working condition and convenient operation.
Spiral classifier is a type of classifying machine that classifies materials based the principle that the solid particles with different sizes and proportions have different falling speed in the liquid, and fine ore particles float in the water and coarse ore particles sink to the bottom of the chute and the coarse ore particles are pushed by the spiral to the upper part and discharged.
