Introduction of Biomass Wood Pellet Production Line
1.The production line includes wood crushing (if the raw material is not already granulated),material sieving, drying (if the raw material contains too much moisture), pelletizing, cooling, screening and packing. The whole pelletizing process can be highly automatically controlled and customized.
2.This is whole system automatic production line with different capacity demand and raw materials information.
3.The production line could suitable for raw materials like: rice husk, sawdust, rice straw, cotton stalks, cornstalks, peanut straw, grape straw, dry hay,grass, forest wood logs, forest wood branch, forest wood waste, wood waste, etc. Kinds of biomass waste.
4.High density, smooth surface, 6mm diameter or 8mm diameter, 33mm (20-50mm adjustable)length pellets you will get.
What Materials Can Be Pelletized in a wood pellet plant?
Nearly all forestry and agro-waste material can be made into wood pellets
by our wood pellet mill, such as: Wood Chips, Shaving, Sawdust, Groundnut-shell, Sugarcane,Caster Shells/Stalk, Coffee Husk, Paddy Straw, Sunflower Stalk, Cotton Stalks, Tobacco Waste, Mustard Stalk, Jute Waste, Bamboo Dust, Tea Waste, Wheat Straw, Palm husk, Soybeans Husk, Straws, Rice Husks etc.
Wood pellets application:
As a matter of fact, sawdust pellet made from waste wood is a good kind of fuel 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.
Main Machines of complete wood pellet production line:
1. Wood chipper( crush the big wood into small wood chips)
2. Hammer mill( to grind the wood chips, rice husk, etc into smaller size below 6mm)
2. Dryer ( dry the raw material to proper moisture before making pellets)
3. Pellet making( press raw material into pellets)
4. Cooler( cool down pellets and remove some moisture)
5. Sieve(remove dust, and broken pellets)
6. Packing scale (pack pellets into bags of required weight, like 15kg/bag)
Main process in a wood pellet plant:
Crushing process - wood chipper and wood Hammer mill
The best material size for supporting to produce pellet is 1-5mm. Thus if your
material diameter exceed 5mm, then you need crushing machine to crush and grind them into small powder 1-5mm. Our LYGX series wood chipper and MFSP series hammer mill are your best choice. After milled, the output size can reach 3-5 mm, then it is pushed to next process to get dried and pelletized.
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 biomassmaterial.
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 millis 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.
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.
Please kindly note:
Not all these processes are necessary for you. These are common processes
for your reference. we will customize the complete solution as per your raw
materials condition and your request for capacity.
