Study on Theory of Separation Efficiency of Twin-Spiral Separator in a Grinding-Separation Apatite Process

Study on twin-spiral separator in a grinding - separation apatite process is presented. The evaluation of separation efficiency of the solid - solid separator by gravity sedimentation such as settling tanks or by centrifugal such as cyclone, centrifuge equipment in chemical industry is necessary. This study shows a method to evaluate the separation performance of a separator using the theory of separation efficiency. The method has been applied to the twin-spiral separator in a grinding - separating process at Vietnam Apatite Mineral Processing Company.
