Raymond Mill

Technical Advantages

Unique wear proof perching knife design

The combined-type shovel blade can reduce the cost of wearing parts, with only the blade to be replaced during maintenance; the design of its curved shovel blades can change the feeding angle and prolong the service life of the roller and ring, up to reduce the operating costs.
 

Arc air duct design

The circular duct can avoid air energy loss and ensure transportation efficiency; the high-strength guard plate can protect the working face of the air duct.
 

Cone Gear Whole Transmission

The bevel gear integral transmission can achieve higher transmission efficiency, save space, and lower investment costs.
 

Volute design

The unobstructed wear-resistant volute can effectively improve the efficiency of the wind-driven transmission in the mill and simultaneously reduce the costs for material maintenance.

　　Working principle

　　In the main unit's working process, the grinding roller device not only performs gyration by surrounding the central axis，but also performs revolution by surrounding the grinding ring. The grinding roller itself self-rotates by rubbing effect, the merit of which is that it can not only fully pulverize material, but also ensure uniform wear around grinding roller, increasing the service life of grinding roller. perching knife, which is installed under grinding roller hanger, rotates with grinding roller at the same time. In this process, the perching knife throws up materials and feeds them into a grinding ring of a grinding roller to form a padding layer. This padding layer is pulverized through outward centrifugal force generated by grinding roller(namely extrusion force between grinding roller and grinding ring)for the purpose of pulverization.
