China famous excellent quality ring die wood

biomass sawdust pellet mill 

Features and Advantages

a. Main transmission of the machine adopts the high precision gear transmission. The ring die uses the quick release clamp type which improves about 20% efficiency compared with that of belt driven.

b. The whole machine uses the high quality imported bearing and oil seal, making the transmission efficient, stable and low noise.

c. Internationally advanced level compensatory type snake shape spring coupler characterizes with novel and compact structure, safety and low malfunction.

d. The specifically made feeding structure makes the raw materials get into the machine in an even and reliable way. It is designed especially for the pelletizing of the light materials with the proportion of 0.3-0.6g/cm³.

e. The whole machine equips with overload protection device which fully take into the consideration of the protection to the main machine in the process of making pellets.

f. The rotating speed of the feed auger can be adjusted which can be suitable for all kinds of capacity requirements.

g. Alloy steel ring die is manufactured by adopting internationally advanced equipment and technology. Its has long service life, the finished pellets are smooth with better quality.

h. This machine is equipped with die hoisting device. Users can change the die easily.

Industrial Application

The sawdust pellet making machine is widely used in biomass-energy fuels plant, power plant, wood processing plant,fertilizer plant, chemical plant etc. 

Working process of MZLH series biomass wood pellet machine:

 A. Preparing raw materials:

All the raw materials must be crushed into sawdust before going to wood pellet machine. If not, you may need a wood chipper, wood crusher.
B. Drying process:
Before going to the pellet machine, the moisture of sawdust must be controlled in 10-15%. This process can be realized by a drum dryer.
C. Feeding process:
The dry sawdust is delivered by a conveyer into the stock bin which is installed over the feed hopper. 
D. Pressing process:
After the sawdust delivered into the ring die of wood pellet machine, we can start the wood pellet machine. The sawdust will be pressed through rollers. The resulting pressure compresses the sawdust and extrudes it through the holes in the die.
