Wood pellet is made mainly of sawdust, shavings and fines leftover after processing trees for lumber and other wood products. At a pellet mill the material is dried, compressed, and formed into small eraser-sized bits, they are clean, pleasant smelling and smooth to touch.

Working principle: Adopt gear transition, and make pellets.

The mainly process includes: Crushing(hammering) - drying - pelleting - cooling - packing

1. Crushing Process:
When the thickness of raw wood material is >10mm, and >50 * 50mm(L * W), we need use the Wood Chipper to chip them into small pieces, then crush the small pieces into wood powder with diameter less 3mm by Hammer Mill (Crusher).

2. Drying Process:
The best moisture content to pelletizing is about 13-15%. Our Rotary Dryer is made up of Stove and Main Rotary Dryer, which can realize to reduce the moisture from 60% to 10%. Our stove is fueled by coal, which can save electricity consumption largely.

3. Pelletizing Process:
SZLH Wood Pellet Mill is the most important equipment. Pelletizing is the process of making waste materials into solid fuel-wood pellet which is used for burning purposes
