The QDK high efficiency separator delivers ground material via two diametrically opposed feeding chutes to a rotating material distribution plate. Due to the high rotation speeds the material is thrown between the ring and the rotating cage of the separator. The small particles are drawn into the rotating cage through the blades of the cage and then collected by cyclones or filters. Using filters for the collection process allows the temperature of the grinding can be obtained bprocess to be controlled by adjusting the supply of fresh air. Different material finenessesy regulating the speed of the rotating cage and/or the amount of air in the QDK high efficiency separator.
One of the characteristics of the Christian-Pfeiffer-QDK high efficiency separator is the almost wear-free air seal between the rotating cage and the housing so that the two parts do not touch each other. The air seal between the rotating cage and the housing prevents the coarse particles from passing into the finished product at the end.
