Water content in 20% a 10% corn, cotton straw by slicing and playing a more functional type crusher crushing, due to the use of spindle speed 2900 rpm, 4-8mm diameter of the sieve, so that biomass raw materials by slicing and smashing into 3 - 8mm powder can be directly used to make.

After crushing the material is sent into the hopper through the belt conveyer, and the material is sent to the material feeding hopper by the feeding and the material to the material feeding machine. Due to the use of the ring mode which is suitable for high fiber material granulation, the surface of the particles is smooth and the hardness is moderate. The mold diameter is 8 - 10mm, the material and the pressure roller, the template in the granulation material and the pressure roller, a large quantity of heat generated by the friction between the plate, so that the material is heated to 80 degrees. To soften the wood fiber, and the process of sterilization, the whole granulation process is no longer with another hot or hot steam.

After the belt conveyor sent to the cooling and cooling of the dryer, the upper part of the cooling tower is equipped with a strong suction pipe, draw out the hot steam and moisture, the particles after 3-5 minutes of rolling cooling and hardening of the product to further complete the qualified products.
