Do you find out about biomass pellet maker?

I believe every person has become aware of biofuel pellets, so just how is it made? First, put the raw products (such as sawdust, straw, etc) for making biomass pellet fuel right into the barrel of the biomass pellet maker feeder. Due to the fact that it is turning, it is easy to toss the raw products to the inner wall under the activity of centrifugal pressure.
