Roller Driven Wood Pellet Machine

What are the differences between D type pellet mills and R type pellet mills? 

D type, literally is called rotating die type while R type is called rotating roller type. Mechanically, the prominent difference lies in motion pattern of die and roller, and transmission components. In terms of price, with the same configuration (capacity, power, etc), D type pellet mill is cheaper than R type because the latter has smarter design of pelletizing process and a better gearbox, though both types of pellet mill are competent of making quality pellets.

Working principle of the wood pellet making machine

1.It can process the oil cake and other mixed waste material to granule at one time. And it is columned granule feed and have slippery firm.
2.During the process of producing granule, the temperature can almost reach 70 to 80 centigrade. It can make flour into paste. The inner granule is cooked and fully penetrated, so that not easy to go moldy and degenerative. Then it can be stored for a long time and improve poultry dainty and assimilation function.
