Biomass Fuel Pellet Production with Rice Husk

Rice husk is a good raw material for the production of biomass fuel in agricultural waste.

As long as the moisture meets the requirements, the rice husk can be pressed into cylindrical pellets directly with a pellet making machine, and the diameter of the formed pellets can be 6/8/10 mm.


Generally speaking, using rice husk to produce pellets requires a total of four steps: drying-pelleting-cooling-packaging.
Drying Section

non-essential equipment


In order to ensure the output and the formation of particles, the moisture content of the raw materials must be 10%-15%. If the moisture content of the raw material is higher than 15%, you need to use a dryer to reduce the moisture.

Pelletizing Section

compulsory equipment


The full process is a complete physicay change. By the spinning of the main shaft, it drives the rollers of the pellet mill to push the materials into the trumpet haped holes of the pellet mill ring die, and the materials are firmly compressed into shape. There are no any chemical adeheres are applied at all.

Cooling Section

optional equipment


When the pellets are freshly made out of the machine, because it’s from fully physical work, the termperature is very high, thus with the help of the cooling machine, not only the pellets could be cooled down, but also it could store the pellets for a while, stressen the pressure of packing & convening sections.

Packing Section

optional equipment


Under the action of the packaging machine, the pellets are packed into the bag according to the required weight, and the bag is automatically sewn. Convenient for transportation and sale.

The moisture content of scraps is less than


If moisture is higher, need to use dryer to reduce the water content before pelleting section.

Producing Instances

  • We establish one 2-3 t/h wood pellet line in Wen zhou, Zhe Jiang Province in China.

  • The raw material is sawdust and wood block.

  • The moisture of raw material is less than 20%.
