Powder Classifier

Powder Classifier

[ Capacity ]: 1- 80 tph

[ Applicable Material ]:

Efficient Powder Separator is the latest powder separating equipment developed by our company, the separating rate could reach 85% -90% or more.


Air classifier is mainly used for raw meal clinker classifying and setting up close-circuit grinding system with ball mill. It is widely used in powder process, cement, chemical, metallurgical and other industries.

Working principle:

Air classifier often work with ball mill, forming a closed- circle production plant.it can improve ball mill capacity and get required material size. it's widely used for cement production, fly ash production, sand production and so on. more than 300mesh powder can be get. 

In working condition,high speed motor drives the vertical transmission shaft to rotate through the transmission device. The material access the chamber of separator by the feeding port which on the top of separator, then falls on the scattering plate by two pyramidal which set in the coarse powder collecting cone and powder pipe. The fine powder which satisfied demand will enter inside through the cage rotor,with circulating air enters the high efficiency and low resistance cyclone separator, then slipped into fine powder collecting cone into a finished product.


1. Using flexible combined propeller bulk plate.
2. High grading accuracy.
3. Spindle speed can be changed by adjusting motor speed, fine adjustment is easy.
4. Using low resistance with high efficiency cyclone dust collector.
5. Particle size distribution is more reasonable, final product quality has been improved significantly.
