How to Make Biomass Wood Pellet?

Wood biomass is a common seen pellet production raw material, which includes timber, logs, chips, shavings or sawdust of pine, acacia, cypress, beech, oak, and so on. Generally if your raw material is softwood, you can pelletize it without adding additive; if your raw material is hardwood, you need to add certain amount of softwood or binder (hardwood is comparatively difficult to pelletize).

The wood biomass pellets production technology goes this way:

1. Raw material crushing: usually wood chips, logs or timber, etc. must be crushed before pelletization. The reason is that these wood raw materials are large pieces and can’t be pelletized directly. This process will need wood chipper and hammer mill.

2. Crushed material sieving: sometimes the raw materials have impurities like stones or metal scraps. These impurities will destroy the pellet mill. So they shall be sieved.

3. Drying: the sawdust usually contain much water. In this case, the dryer is indispensable. For capacity below 1ton/h, air flow dryer is enough. But for large capacity, drum dryer is good help.

 

4. Wood biomass pellets production: the wood pellet mill also has different capacities. 50-500kg/h, use flat die pellet mill; >500kg/h, use ring die pellet mill or multiple sets of flat die pellet mill.

5. Pellets cooling and sieving: the pellets have high temperature when produced by the pellet mill; as a result, a cooler is needed to cool the pellets. Besides, the counter flow cooler can also sieve the broken pellets or raw material powder to get good quality pellets.

6. Pellet packing: to pack the wood biomass pellets in bags will make them easy to store, transport and sell. They can be packed into small bags and large bags.

Above is whole wood pellets production line process, and other biomass raw materials go similar steps.

Biomass Pellets Application

1. Industrial boiler: bio-pellets can partly(or entirely) replace coal or fossil fuel in co-firing heating for large-scale industrial operation to reduce the energy cost.
2. Power plants :biomass pellets can be used in power plants to solve the problem of insufficient power supply.
3. Animal bedding:bio-pellets made of softwood is a kind of slap-up animal bedding to raising animal experience.
4. Building heating: biomass pellets can be used in a pellet stove or furnace to heating room at school, hospital, marketplace, company, etc. Cooking with biomass pellets is also available.
