Application and usage The vertical ring die pellet machine is suitable for the materials with low adhesive and low formation rate, which are difficult to pressing molding, such as rice husk, sunflower seed husk, peanut shell, a variety of wood waste like branch, trunk, bark, various of crop straw, eucalyptus, palm fiber(EFB),coffee shell, sawdust and so on. Main functions and features: 1.vertical feed and directly in place 2.Die static, the roller rotating, and material centrifugal, evenly around 3.Double layers die, down and up dual usage, low input, cost efficiency and energy saving 4.Ring die, vertical structure, granulating chamber cooling 5.Separate discharge device to ensure the forming rate of pellets, reasonable design 6.Main parts adopts high alloy wearable materials, and double lifetime 7.24 hrs working with automatic lubrication system Complete Pellet production line process: (a) Peeling Process Wood debarker machine is applicable to peel the log of MDF board and papermaking industry, it is mainly used to peel log, small wood and so on, the peeled rate is more than 95 percent. (b)Chipping Process In the pellet plant before raw materials are made into biomass pellets, they are first reduced into much smaller, uniformly-sized particles. When the thicknedd is larger than 10mm or the size is greater than 50*50mm, a chippper is needed to chip these materials into smaller pieces. (c)Grinding Process The hammer mill is used to further crush these small pieces into particles of less than 3mm in diameter. (d)Drying Process After raw materials are crushed a dryer is needed since most raw wood materials have a moisture content of about 50%. However, the optimal moisture content for pelletiztion is 13%-15%. Therefore a rotary dryer is included in the pellet plant to reduce the moisture content. After crushing and drying you can begin making wood pellets. (e)Pelletizing Process After crushing and drying the raw material properly it is then ready for the pellet mill. The pelletizing machine or press is the key piece of machinery in the pellet plant. It should be mentioned that impurities in the raw materials like metal or stone,may damage the die and rollers of pellet making machine. (f)Cooling Process Usually after pelletizing, the temperature of pellets is between 60-80 degrees and the moisture content is close to 15%. For storage purpose, a cooler must be used to reduce their surface temperature and moisture content. (g)Packing Process Finally is the packing process. In order to protect the wood pellets becoming getting damp and to increase storability, proper packing is necessary.
