Pelletizing is the process of making waste materials into solid fuel-wood pellet which is used for burning purposes.

Raw materials:

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.Pellet Plant

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

Gear drive; SKF bearing; Auto-oiling;Auto-adjusting feeding; Adopting Japanese Steam adjusting system; Auto-adjust steam lnlet; 24h ours continously working. Auto-adjust quantity of feeder by electrical current of pellet mill via screw feeder with frequency modulation and speed adjusting; Conditioner is made by Stainless steel; Access door at side; This design is easy to exam; The ring die made by stainless stee

4. Cooling Process:
After the pelletizing process, the temperature of the wood pellet is about 60-80 degree, and the moisture content of the wood pellet is about 15%, so we need use Cooler to reduce about 3-4% moisture, such this the wood pellet is easy to store.

But considering the feedback from some foreign clients, the local climate is very humidity; they hope to cool the wood pellet with moisture 7-8%. In order to satisfy the different need from different clients, we develop one kind of new Stabilizer Combined Cooler.

5. Packing Process:
After cooling, the wood pellet will not directly enter into the fuel process, avoiding the wood pellet affected with damp. The packing process is necessary. In this process, we assemble our domestic best Semi-Auto Packing Machine to you.
