1. Raw material:

Pellet fuel is mainly made of sawdust, shavings leftover after processing trees for lumber and other products. The raw material also can be corn or other biomass material.

2. Introduction of Process:

At a wood pellet mill, the material is dried, compressed and formed into small erase-size bits. They are clean, pleasant to smell and smooth to touch.

3. Detailed Product Description:

(1) Wood Pellet Mill: Pulverizing System

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 System
 

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

(3) Pelleting System

Driven with heavy- duty gearbox construction can produce continuously in most adverse condition. The importment key elements are of high performance with long life and low maintenance cost. The key parts are made of alloy steel to be very strong and malleable. Die is made of stainless steel. Pellet machine is widely used in the granulation of wood, straw, and other biomass sources. Capacity ranges from 200kgs to 3T per hour.

(4) Cooling /Sieving /Bagging system

After the pelletizing process, the temperature of the wood pellet is about 60-80 degree. The moisture content of the wood pellet is about 15%, so we need use a Cooler to reduce about 3-4% moisture. This wood pellet is easy to store.
