  • Description: Mechanical centrifugal air classifiers are used extensively to process aggregates, ceramics, chemicals, foods, minerals, metals, plastics, flyash and other materials. They are normally employed when the particle size that you need to separate is too fine to screen. Air classifiers eliminate the blinding and breakage issues associated with screens. They work by balancing the physical principles of centrifugal force, drag force, collision and gravity to generate a high-precision method of classifying particles according to size and density. Mechanical centrifugal air classifiers are useful in many applications, including the following: 1. dedusting undesireable fines in many types of aggregate stone, 2. Reducing the fines load on a water flotation system for extracting precious metals from many types of minerals, and 3. increasing the protein content in wheat flour, chick-pea flour, poultry-meal animal feed and others. The performance of mechanical centrifugal air classifiers can be evaluated by analyzing the cutpoint, tolerance, yield and efficiency.
