The round closed auto-lubrication system for wood pellet mill adopts the tracing and inspecting system controlled by the microcomputer for the roller and pressing

cavity,which completely solves the trouble of lubricating roller depending on the operation experience and guarantees the continuous pelleting production.

The pressing cavity inspecting system of Tiannong patent technology solves the problem of high temperature harm caused by illegal operation and effectively prevents

the dust explosion and fire hazard of high temperature.

The ring die and roller have the fine machining with the alloyed steel and take the carburizing and heating treatment to the depth of hard facing to 2mm,saving the

production cost at the maximum.

The driving gear adopts the high precision gear transmission structure,Swedish imported bearing,and the hoop fastening method of ring die. As the result, the capacity

is 10-15% higher than the belt transmission structure. 

The conditioner and ring die safety cover are made of stainless steel in order to prevent the  water vapor corrosion damage of long time using.
