1 Crushing Process:
When the thickness of raw wood material is more than 10mm, and length*width is more than 50 * 50mm,we need to use the Wood Chipper to chip them into small pieces, then crush the small pieces into wood powder with diameter less than 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 the goal of reducimg the moisture from 60% to 10%. Our stove is fueled by coal, which can save electricity consumption largely.

3 Pelletizing Process:
MZLH wood pellet mill are equipments of great importance, which have the following features:

1). The lubrication system for wood pellet mill adopts the tracing and inspecting system controlled by the microcomputer. When the temperature of the bearing is over the normal temperature, the microcomputer will start the Auto-Lubrication System to lubricate the bearings, which will completely solve the problem of lubricating roller depending on the operation experience. The Lubrication System is made up of the tracing and inspecting system controlled by the microcomputer, auto-lubricating system on time and compelled lubricating system by hand.

2). Driving Gear adopts the high precision gear transmission structure. The wear bearing is SKF from Sweden. The ring die adopts the hoop fastening method, which is increasing the speed of discharge compared with the past bolt fastening method. As a result, the capacity is 10%-15% higher than the belt transmission structure.

3). As for the ring die and roller of the wood pellet mill, we have the fine machining with the alloyed steel. And our heating treatment is also different from the other domestic manufacturer.Our carburizing treatment make the depth of hard facing to 2mm, which increace the quality of anti-abrasion of the ring die and roller more than 10 times. As a result, it can save the production cost largely.

Additionally, we have developed a kind of new Air Current Rotary Dryer, which can reduce about 30% of energy consumption compared with the old Rotary Dryer.

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%.Then we need to use Cooler to reduce about 3%-4%of the moisture so that the wood pellet would be 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 different needs from different clients, we develop one kind of new Stabilizer Combined Cooler.

5 Wood Pellet Mill Packing Process:
After cooling, the wood pellet mill 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.
