The Frequently Asked Questions About Small Pellet Mill

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.

How to tell D type from R type from appearance?

Instead of rotating die plate, the two rollers are running around the central driven by the main shaft and simultaneously rotating themselves, adding a positive force to the raw material. With the given dual action, not only is the raw material well pressed, but also mixed. Thanks to the sturdy shaft, it easily resists the harder counterforce produced by hard wood and material suchlike, making R type therefore a wider material application range.
