Working principle

The compressed air via dryer is sprayed into the grinding chamber through Laval jet nozzle, the material at the intersection of airflow is crashed, the powdered material enters into the classifying area on the top together with uprising airflow, under the action of centrifugal force from classifying wheel and draught fan, the oversized powder is repulverized and the qualified powder is collected by the cyclone and bag filter.

Can be combined with multistage air classifier to get different particle size at one time, the particle size distributed region is very narrow and centralized.

Feature

1.Superfine and uniform particle size and fineness can be D97=2micron.

2.Build-in turbo classifying wheel is free of over crushing.

3.Expanded compressed air at the outlet of nozzle produce low temperature, which reduce the quantity of heat from size reduction, suitable for grinding heat-sensitive and low-melting-point materials.

4.The system is free from impurity in operation.

5.There is no rotating device in grinding section, little abrasion and low noise.

6.Compact structure, easy installation and dismantlement.

7.Heat-sensitive, inflammable and explosive materials can be ground with inert gases, which can be cycle use.

8.Automatic operation.

Application

Chemicals: pharmaceutical, metallurgy, abrasives, non-metallic minerals, battery anode and cathode materials, talc, kaolin, quartz, graphite, flame retardant, ceramics, pigments and food additives, etc.
