rotating roller pellet mill

The rotating roller pellet mill has a series of rotating rollers and a stationary die. When the pellet machine is in operation, the die is stationary while the rollers are rotating. The great force between the rollers and the flat die will press the powders of raw materials through the holes in the die to form biomass pellets. The rotating roller biomass pellet press’ design prolongs its service life, which is about 2000 hours. Besides, the quality and length of the finished biomass pellets are much smoother and longer.

The diameter of final finished biomass pellets is from 6mm to 10mm. The flat die and the rollers are both made of high-quality alloy steel, and their service life is at least over 800 hours.
Besides, the usable life of motor and gear box is 1 year; the upper body and box of main shaft is 5 years; for others not stated here: 1 year.

Biomass pellets are a kind of clean, efficient, cost-effective, convenient, economical, renewable, and environmentally friendly fuel. They are made of various kinds of biomass materials, such as: rice husks, wood shavings, wood chips, sawdust, straw, alfalfa, bagasse, peanut shells and forest waste, etc.

The biomass materials need to be pulverized into small particles first. And then make sure they contain the proper moisture, usually less than 15%. Then put these biomass powders into the feeder of the pellet mill, and they will be pressed by a series of rollers into the small holes of the die inside the pellet machine. Due to the high temperature and strong pressure inside the pellet press, the lignin, naturally contained in the biomass materials, melts and acts as a "binder" stitching together fibers to form an extruded pellet section and helping to keep the shape of pellets as they are dried.
