Introduction of sawdust pellet production line
The sawdust pellet production line is a whole system automatic production line which suitable for raw materials like: sawdust, rice husk, rice straw, cotton stalks, forest wood waste, wood waste and other biomass waste with different capacity.
Application of wood sawdust pellet line
Today, the biomass energy as a good kind of green, low carbon, environmental-friendly fuel has been used to replace traditional fossil fuels like coal, gas, petrol, etc.
1.Burning in a stove to cook at home;
2.Heat the house, school, hotel, or greenhouse, farm;
3.Used in thermal power plants to replace coal.
4.Used as cat litter to replace clay;
5.Used as horse bedding, or beddings for cow, chicken, dogs, and other animals.
Flowchart of wood sawdust pellet line
The wood sawdust production line includes material sieving, drying (if the raw material contains
too much moisture), wood pellets pelletizing, cooling, screening and packing.
Main Machines of complete wood pellet production line:
1. Pre-cleaning( to remove the impurities in the raw materials)
2. Dryer ( dry the raw material to proper moisture before making pellets)
3. Wood pellet mill ( press raw material into pellets)
4. Cooler ( cool down pellets and remove some moisture)
5. Screener (remove dust, and broken pellets)
6. Packing scale (pack pellets into bags of required weight, like 15kg/bag)
Main process of wood sawdust pellet line
Pre-cleaning process - pre-cleaner
To remove the impurities in the raw materials such as stone or some too big materials.
Remark: This process is optional. If the raw material is clean, it is not necessary.
Drying process - Rotary Dryer
The best moisture content to pelletizing is about 12-18%. Our rotary dryer is made up of burning stove and main rotary dryer which is high efficient in drying the wood and biomass material. It can realize to reduce the moisture from 50% to 10%.It is very important for wood pellet plant to using moisture detector which will determine the most suitable moisture before pelletizing.
Pelletizing process - Wood pellet mill
Wood pellet mill is the heart of the wood pellet production line, and has reliable running performance. It is special designed for compacting of wood, straw, and other biomass sources into pellets. Capacity ranges from 1T to 10T per hour. Our MZLH series Ring die pellet mill is best choice for large scale production.
Parameters of wood pellet mill:
Main motor power(kw)
Ring die dia(mm)
Cooling process - Counterflow cooler
Usually after pelletizing, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purposes,a cooler must beused to reduce their surface temperature and the moisture content, also help screen good and pure pellets.
Packing process - 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.Remark: We can customize the complete solution as per your raw materials condition and your request for capacity.
