Wood pellet machine
Ring die pellet machine also named as pellet mill is a technical pellet machine for industrial wood pellets processing. The common raw materials for making wood pellets are: wood sawdust, crushed wood logs, crushed wood waste and so on. Besides, it also has a wide application for biomass materials pellets such as: grass pellets, cotton stalk pellets, rice husk pellets, etc. With a large capacity, ring die pellet machine is common used in industrial wood pellet plant for large capacity biofuel pellets processing.
Process of Complete Wood Pellet Production
Raw materials Preparation
Wood pellets can be made from sawdust, wood shavings, wood chips or wood logs, any forestry wastes or biomass straws, stalks, etc.
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.
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
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.
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
