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.
and chemical processes are used to extract the desired product Abstract— A study on physical beneficiation of platinum group metals (PGMs) flotation tailings was carried out by means of spiral classifiers and a gravity separator (Knelson Concentrator KC-CVD –
Spiral classifiers separate the fine waste material from the oversized material that needs to be sent back to the regrind circuit for further size reduction in ore processing. They also serve a dual purpose as a dewatering screw, when the amount of water on site is at a premium.

Mar 16, 2017· Reflux Classifier technology is gaining popularity in coal processing applications across Africa because of its ability to easily handle varying feed conditions.Traditional technology cannot accommodate these feed variations resulting in recovery losses whereas the Reflux Classifier is a lot more forgiving of solids feed rate variations.
This prevents the sieve frame deformation caused in the course of falling. Protect a fixed role. So greatly extended the use of the sieve and sieve frame time, and can reduce the material loss.Secondly, in the crusher built-in rotor movement test equipment before leaving the factory, test their balance.
