What is the production method of biomass pellet fuel?

1, raw material yard. Biomass wood chip fuel raw materials to sawdust-based, in order not to affect the production of fuel, it is best to prepare enough raw materials, at least to ensure that about 15 days of raw materials production needs.

2, screening. Through the nylon conveyor will be transported to the sieve raw materials for screening, screening out the larger pieces of wood or wood nails and other debris.

3, dry. The production of biomass wood chip fuel is very strict in the water content of raw materials. After the screening, it is transported to the drum dryer through the nylon conveyor to dry by hot air.

4, cyclone separation. After the raw material is dried, there may be a lot of moisture in the process of transport, so the moisture needs to be drained through the cyclone.

5, material delivery. This link requires the corresponding transmission equipment, according to the need to yo ah, you can use the screw conveyor, nylon conveyor and hoist to the material transported to the appropriate equipment.

6, granulation molding. Sawdust burning granule molding machine is the key equipment of the production line, the equipment can use sawdust, corn stalks, bean stalks, cotton straw and peanut shell and other raw materials, processed from the wood burning particle density can reach 1.0-1.3 tons / cubic meter.

7, cooling. Just out of the wood chips temperature up to 80 ~ 90 ℃, the structure is more relaxed, easy to break, to be through the counter-current cooling system, cooled to room temperature before bagging or conveyor belt and conveyor into the silo.

8, screening. But also the last part of the link, that is, after the cooling of the pellet fuel, the use of shaker screening, scraping and other sieving out to ensure that the quality of biomass wood chip fuel
