Raw Materials Preparation
Wood pellet mill
Wood pellets can be made from sawdust, wood shavings, wood chips or wood logs, any forestry wastes or biomass straws, stalks, etc.
Wood chips from wood crushing machine
Raw Material Crushing Process
Crushing machine is used for crushing the larger materials into smaller powder for supporting produce wood pellets. Wood crusher is ideal equipment for crushing raw materials like square logs with diameter less than 200mm; if the material has a diameter less than 50mm, then wood hammer mill is the best choice. The best thickness of the wood chip is less 5mm. After milled, the output size can reach diameter 3-5 mm,which is convenient for further processing to get dried and pelletized.
Biomass Material Drying Process
The best moisture content to pelletizing is about 11-17%. So before pelletizing, a drying machine is needed to make the moisture content reaches the required standards.
Raw material and final wood pellet
Wood Pelletizing Process
Pellet mill is the significant part of the wood pellet production line, and has reliable and stable performance. Capacity ranges from 1T to 10T per hour. You can choose ring die pellet mill or flat die pellet mill depend on your capacity requirements.
Wood Pellet Cooling Process
After pelletizing process, the temperature of wood pellets is between 60-80 degrees and the moisture content is close to 15%. So a cooler must be used to reduce their surface temperature and the moisture content which makes the wood pellets easy to store, meanwhile helps screen good and pure pellets.
Wood Pellet Packing Process
After the cooling process, packing process is necessary to protect the wood pellets from the damp. Amisy automatic wood pellet weighing & packing system adopts PLC control with high weighing accuracy and easy operation is your best choice.
