Pelletizing standard of biomass wood pellet machine equipment

1. Shredded sawdust: sawdust from sawdust with a band saw. The produced pellets have stable yield, smooth pellets, high hardness and low energy consumption.

2. Small shavings in furniture factory: Because the particle size is relatively large, the material is not easy to enter the wood pellet mill, so it is easy to block the pellet mill and the output is low. However, the small shavings can be granulated after being crushed. If there is no crushing condition, 70% wood chips and 30% small shavings can be mixed for use. Large shavings must be crushed before use.

3. Sand polishing powder in board factories and furniture factories: the specific gravity of sand polishing powder is light, it is not easy to enter the granulator, and it is easy to block the granulator, resulting in low output; due to the light specific gravity of sand polishing powder, it is recommended to mix with wood chips and granulate together. Can each account for about 50% to achieve the granulation effect.

4. Leftovers of wood boards and wood chips: The leftovers of wood boards and wood chips can only be used after being crushed. It is recommended to pulverize the particle size to reach the sawdust particle sample sawed by the band saw, use a high-speed pulverizer, use a 4mm chip, the particle output is stable, the particle is smooth, the hardness is high, and the energy consumption is low.

5. The raw material has been mildewed: the color has turned black, the soil-like raw material has serious mildew, and cannot be pressed into qualified granular raw materials. After mildew, the cellulose in the wood chips is decomposed by microorganisms and cannot be pressed into good particles. If it must be used, it is recommended to add more than 50% of fresh wood chips and mix it. Otherwise, it cannot be pressed into qualified pellets.

6. Fibrous material: The length of the fiber should be controlled for the fibrous material. Generally, the length should not exceed 5mm. If the fiber is too long, it will easily block the feeding system and burn the motor of the feeding system. For fibrous materials, the length of the fibers should be controlled. Generally, the length should not exceed 5mm. The solution is to mix about 50% of wood chips for production, which can effectively prevent the feeding system from clogging. Regardless of the amount added, you should always check whether the system is blocked. fault, to prevent the occurrence of faults such as burning and damaging the motor of the feeding system.
