Lini Produksi Pelet Keripik Kayu

As the wood chips raw materials are mainly forest felled materials, woodland miscellaneous irrigation materials, etc., it is necessary to collect the raw materials at this stage and remove the large wood blocks and debris through the roller screen.

The task at this stage is to further crush the wood chip raw material into small wood sawdust.Only wood chips that meet the size requirements can be directly fed into the hammer mill, or those that have passed the chipper and coarse crushing and require further fine powder. Due to the wide range of screen sizes on the hammer mill, it can produce particles of various sizes, so it is the most common choice for wood pellet manufacturers.

After crushing ,materials due to the existence of air circulation inside of hammer mill and can not drop down by gravity ,so we add a draught fan and cyclone with dust collector here, to provide the strong wind for breaking the circulation , in order to the final wood sawdust drop down and also keep the environment clean.

For drying part, you can adjust the feeding speed, the rotating speed of the drying machine, and the inlet air temperature to adjust and to get the required moisture to make wood pellets. And the suitable moisture to make wood chip pellets is 15%-17% . ( About how to adjust, our engineer will train your labors) Different capacity, the diameter and length of the drying machine is different.

Whether producing single raw material pellets or mixed pellets, maintaining the consistency of raw materials is very important for pellet production plants. After the raw materials are grinded and dried, binder(vegetable oil, molasses, starch, gluten, dried lees, rapeseed cake, etc.) need to be added，so it is necessary to use a mixer machine. After mixing, the raw materials are mixed more fully and evenly, and then sent to the pellet making machine.

After the raw materials are thoroughly mixed, water and steam need to be added to make the pellets. These additives can help improve the working efficiency of the pellet mill machine.

The wood chip pellet making machine is the heart of the wood pellet production line. The pellet machine is widely used for pelletizing wood, straw and other biomass energy. The output ranges from 1 to 10 tons / hour. The biomass wood pellet machine adopts Swedish SKF bearings and Siemens motors, which can fully guarantee the wood pellet equipment capacity and stable operation.

The temperature of the biomass wood chip pellets after granulation is as high as 80-98 degrees, the structure is relatively loose, and it is easy to break. It must pass through a counter-flow cooling system and be cooled to room temperature before entering the warehouse.

The forming rate of wood chip pellets is around 98% , so there are still have 2% powder in pellets, by screening, sort out all the powders from pellets.

The qualified wood chip pellets are packed into plastic bag from 10kg to 100kg(Now more and more biomass pellet processing plant choose tonnage scales).Then use thermoplastic sealing machine to sew, these can make the pellets dry and water-proof.To extend the wood chip pellets storage time .(The pellets should be kept from the direct sunlight, which may higher the storage temperature and increase the chance of fine percentage.The pellets should be kept in a well ventilated place because monoxide gas may be released from the wood chip pellets stored, especially in a warm environments. Be aware of the CO poisoning.)
