1TPH--10TPH Ring die Biomass wood chips Eucalyptus pine birch poplar complete pellet production line

Biomass pelletizer is to extrude agricultural and forestry processing wastes into high-density Pellet fuel through pretreatment and processing, which is suitable for a wide range of raw materials.

Raw material :

All kinds of waste wood, branches, bark, sawdust, wood scraps, rice husks, peanut shells, fungus residues, reeds, crop straws, etc. can be used for processing and shaping Pellet fuel. Usually in the shape of an 8mm pellets.

Advantages :

it has the advantages of being large in weight, small in volume, resistant to combustion, and easy to store and transport. The compressed volume is about one thirtieth of the original, the density is 0.8-1.4, and the calorific value is between 3400-5000 kcal. It is a new type of Bioenergy, and also an ideal fuel to replace coal. Widely used in household heating, industrial boilers, hot water boilers, grain drying, and biomass power generation fields. At present, there are two main types of biomass pellet machines commonly used in the industry, namely flat mold pellet machines and ring die grinding pellet machines.

FAQ :

Five main reasons for poor particle manufacturing performance of biomass pellet machines:
Some produce a large amount of powder during the processing, while others produce unsmooth particles that do not sell well, and so on.
Reason: There are generally five main reasons for poor granulation effect:
1. The mold needs to be ground. The first time a newly purchased biomass pellet machine is turned on, it needs to add about 10% engine oil to the compressed wood chips to grind the mold of the particles. This step is crucial, as the ground mold can produce beautiful and smooth particles.
2. The moisture content of the raw materials does not meet the standard. Whether it is straw or wooden raw materials, there are requirements for moisture. Forming too wet is not good, and powder is easily produced if it is too dry. It is best to control it between 15-20%.
3. Regarding the particle size of raw materials, it is recommended to process wood chips with a growth rate of 1-5mm. If they are too coarse, the particle forming rate will be low, and the pressure roller mold will be severely worn. If they are too fine, it will increase the energy consumption of the crusher.
4. Unreasonable operation. The most common issue is the gap between the mold and the pressure roller assembly, which cannot be extruded without a suitable gap.
5. Mechanical faults: such as damage to the bearing mold pressure wheel, lubrication system issues, etc.
