Principle:
The product to be ground is fed from above via a rotary airlock directly into the grinding chamber through the classifying chamber where particles are bumped mutually and strongly against the impact beaters, meanwhile, to be impaceted frictionated and sheared in the gap between the impact beaters and liner. The pulverized product is conveyed to the ultra-fine classifier. The end product is discharged through the blow-out opening, the coarse material rejected from the classifier is recirculated for further grinding.

Features:
• The machine is new combined equipment which is composed of grinding and classification in one machine, conpact construction.
• The machine is unrivalled ease of cleaning inspection and maintenance because it is equipped with an separation mechanism, easy opening the grinding chamber and classfing chamber.
• Powder production capacity. The maxmum rare-material particles with diameter is permitted approx. 15mm. It can randomly select powder particles with a diameter range from 8-150um.
• It is universally applicable for almost all products up to a hardness of approx. 3.5 Mohs. It is also adaptable to the pulverization of approx. 7 Mohs hardness if use speacial wear-resisting material.
