Product Application

Log pellet production line Brief Introduction:

After debarking the branches and trunks of logs, the logs are cut into small chips by the chipper.

The size of the chips is 20-30mm and the thickness is 5-10mm, then be finely ground into the sawdust of 3-4mm by the hammer mill;

next, the raw material with 40% moisture is dried to about 15% through a three-layer drum dryer; finally is pelleted,

the diameter of finished pellets is 6-10mm for choosing. After pelleting and cooling,

it is packed into 20-50kg/ bag by small bag packing scale for convenient transportation and sale.

The capacity of the log pellet complete project is 17.5-22.5tph biomass pellets line,

the total power of whole line equipment is about 5027 kW, and the plant covers an area of 10,000 ㎡,

including raw material storage and finished product storage. The whole line’s design is compact,

the structure is reasonable, meets the requirements of environmental protection, and can be directed designed according to customers’ requirements.

Detail Processes:

Debarking Process:

Raw material debarking can improve the heat value of finished pellets,

reduce ash residue after combustion of finished pellets and reduce emissions.

Chipping Process:

The chipping process of the log pellet complete project is to process the wood logs into wood chips,

the size is 20-30mm, the thickness is about 5-10mm, and then enter the processing of the following sections.

Grinding Process:

20*20 square screen is adopted to do the first coarse grinding and then to do the drying.

Drying Process:

three-layer drum dryer, after drying, sawdust moisture in about 13-18%.

Fine Grinding Process:

The grinding work has no dust discharge. After grinding,

the sawdust will be transported through pneumatic transmission by the fan suction air pressure.

The hammer mill is a water droplet type structure;

the hammer mill rotor can be operated in forward and reverse directions to improve the service life of the hammer blade;

the direct transmission mode of the motor is adopted.

Pelleting Process:

The diameter of biomass pellet is optional from 6-10mm,

and the biomass pellets have the characteristics of high calorific value,

no pollution and low ash content, which can be widely used in biomass power plants,

biomass steam boilers, household fireplaces, drying furnaces, and biomass gasifiers.

Cooling & Bagging process:

used to reduce pellets temperature and decrease pellets moisture,

pellets temperature is not higher than ambient temperature 5 ℃ after cooling and the pellets moisture around 8-10%,

particle density 650-750kg/m³. According to the customer’s local sales needs,

the appropriate packing scale is selected for customers to sell products more easily.

There are usually two specifications: small bag and ton bag. 20-50kg/bag for small bags, 500-1000kg/bag for ton bags.
