Straw pellet mill, also named as crop stalk pellet machine, is mainly used to process agricultural and forestry materials into biomass pellets. Water content in raw materials like saw dust and straw is an important parameter for the production of biomass pellets. Whether being too high or too low, water content in raw materials can influence the density of biomass pellets.
If water content in raw materials is too low, biomass pellets produced by straw pellet mill of FTM China Machinery will be easy to absorb water in air and change shape. Doubtlessly, density of biomass pellets will be poor. If water content in raw materials is too high, biomass pellets will be still poor in density due to the increased heat transfer coefficient, decreased intermolecular force and poor adhesive force.
After being extruded through the sleeve, biomass pellets can explode due to the high water pressure inside. For this, work of packaging and transportation can be influenced. If water content in raw materials is too high, it will cause the increasing distance between molecules, poor transfer of heat energy, low temperature for molding work, difficult softening of coarse fibers and weak adhesive force.
Therefore, you should improve the temperature for heating raw materials if water content inside is too high.
