1. Raw materials Prepared
Wood Pellets is mainly made of any wood waste and biomass particles, such as wood sawdust, wood shavings, wood chips, wood logs, straw, rice husk, coffee husk etc. At a wood pellet plant, raw material need to be well prepared before pelletizing, then get dried, compressed, and formed into small eraser-sized bits, the wood pellets get from wood pellet plant are clean, pleasant smelling and smooth to touch.
2. Crushing process – Hammer mill
The hammer mill is a machine whose purpose is to crush materials by the collision between the high-speed hammer and materials. Our SFSP series chipping and crushing machine is your best choice. It mill raw material like tree branch, wood shavings, wood chips, wood logs, cotton stalk, corn stalk, wheat straw etc, with size less than 50mm (diameter). After milled, the output size can reach diameter 3-5 mm, then it is pushed to next process to get dried and pelletized.
3. Drying process – Rotary Dryer
After crushing process, the wood and biomass material need to be well conditioned on moisture before pelletizing. The best moisture content to pelletizing is about 14-16%. Our rotary dryer is made up of burning stove and main rotary dryer which is high efficiency in drying the wood and biomass material. It use steam to heat air and contact material to remove certain degree of moisture. It is very important for wood pellet plant to using moisture detector which will determine the most suitable moisture before pelletizing.
4. Pelletizing process - Wood pellet machine
wood pellet machine is the heart of the pellet machine production line. The Pellet machine is widely used in of wood, straw, other biomass sources into pellet. Capacity ranges from 1T to 10T per hour. Our XGJ series pellet mill adopt SKF bearings from Sweden and NSK bearings from Japan, the motors in the wood pellet is from Siemens, high quality components make the pellet mill more efficient and durable.
5. Cooling process - Pellet cooling machine
After the pelletizing process, the temperature of the wood pellet is about 60-80 degrees Celsius, and the moisture content of the wood pellets is about 15%. A cooler must then be used to reduce the moisture content of the wood pellet to about 3-4%, thereby making the wood pellet easy to store. However, some customers said that the local climate is very humidity, they want to cool the wood pellets with moisture 7-8%. It is no problem, our new stabilizer combined cooler can do it well.
6. Packing process - Pellet packing machine
After cooling process, the wood pellets will not directly enter into the fuel process, avoiding the wood pellet affected with damp, the packing process is very necessary. The packing process is effectively handled by our Semi-Auto Packing Machine.
