Introduction of Biomass Pellet Machine

Biomass pellet machine is also called wood chip pellet machine, straw pellet machine, sawdust pellet machine, wood pellet machine, etc. It is an environmentally friendly equipment that converts agricultural and forestry waste into high-density solid fuel. Its core function is to compress loose biomass raw materials into regular particles through mechanical extrusion.

Biomass pellet machine uses biomass raw materials such as wood chips, straw, rice husks, etc. as raw materials, and uses high-pressure extrusion to bond cellulose and lignin at high temperature to form a combustible pellet fuel. Biomass pellet fuel has high calorific value and can replace coal for heating, power generation and other fields

Raw Material for Biomass Pellet Machine

Wood raw materials: including sawdust, shavings, bark, branches, waste furniture scraps, building templates, etc. produced by processing wood such as pine, poplar, and fir. This type of raw material needs to be crushed and screened to ensure that the particle diameter is controlled at about 6 mm and the moisture content is maintained at 10%-15%.

Crop straw: corn straw, wheat straw, straw, rice husk, peanut shell, cotton stalk and other agricultural waste are also common raw materials.

Other waste: such as cloth strips and waste paper in urban garbage, sanding powder in forestry waste, as well as medicinal residues, mushroom residues, etc.

Features Of Biomass Pellet Machine

1.The horizontal ring die biomass pellet machine is a high-capacity, industrial-grade wood pellet machine that can produce pellets from a variety of biomass raw materials.

2.The horizontal ring die biomass wood pellet machine uses horizontally placed dies and rollers to achieve continuous and efficient pellet production with excellent compression and durability, with an output of up to 4.5 tons/hour.

3.Large wood production lines usually use multiple ring die pellet machines for joint production. This type of wood pellet machine is the ultimate choice for large-scale industrial-scale biomass pellet production.

4.It is widely used in large biomass pellet plants and commercial biomass pellet manufacturing companies.

How Does The Biomass Pellet Machine Work?

1.Material pretreatment: the raw materials need to be crushed and the moisture content adjusted (generally controlled between 12% and 18%) to facilitate pressing.

2.Feeding: the material is fed into the pressing cavity by the feeding device and evenly distributed between the ring die and the roller.

3.Compression molding: driven by the main shaft, the roller rotates inside the ring die to force the material into the die hole.The material softens under the action of high pressure and friction heat, is extruded through the die hole, and is formed into strip particles.

4.Cutting and discharging: After the particles are extruded from the die hole, they are immediately cut into the required length by the cutter.
The finished particles are discharged through the discharge port and enter the cooling system or are directly packaged.

Whole Production Line

A complete biomass pellet  production line includes crushing, drying, pelletizing, and packaging units. 

  1. Crushing: Wood blocks, wood chips, or other wood materials are uniformly crushed. This can be done using a wood crusher or shredder to reduce the size of the wood into smaller pieces.
  2. Drying: The crushed wood material is then fed into a drying machine drum through a conveyor belt. The drying process quickly reduces the moisture content of the material to around 12% to 15%. This is important for ensuring the quality of the final wood pellets.
  3. Pelletizing: Once the wood material is dried, it is then fed into a pellet mill. The pellet mill compresses the material under high pressure and heat, forming it into small cylindrical pellets. The pellets are then extruded from the pellet mill.
  4. Packaging: The pellets are discharged from the pellet mill and can be directly connected to a conveyor belt that leads to an automatic packaging machine. The packaging machine packages the pellets into bags

FAQ

A: It compresses agricultural and forestry waste – wood chips, sawdust, straw, rice husks, bark, even cloth strips and paper waste – into high‑density pellet fuel. Our ZZCHRYSO pellet machine turns low‑value residues into clean, high‑calorific fuel for heating, power generation, and industrial boilers.

A: First, the raw material is crushed to about 6 mm and dried to 12–18% moisture. The material is fed into the pressing cavity between a rotating ring die and rollers. High pressure and friction heat soften the lignin, which acts as a binder. The material is forced through die holes, forming solid pellets. A cutter cuts them to the desired length.

A: Wood‑based: sawdust, shavings, bark, branches, furniture scraps, building templates (pine, poplar, fir). Agricultural waste: corn straw, wheat straw, rice husks, peanut shells, cotton stalks. Others: cloth strips, waste paper, sanding dust, medicinal residues, mushroom residues. The key is proper crushing and moisture control.

A: Two models: CRS608 (2.5–3 t/h, 180 kW motor, ring die ∅608 mm) and CRS788 (4–4.5 t/h, 220 kW motor, ring die ∅768 mm). Both use two press rollers. The CRS788 has a water‑cooled synchronous motor and timing belt drive for higher efficiency.

A: CRS608: 180 kW (90 kW × 2), asynchronous motor with V‑belt + gear transmission. CRS788: 220 kW (110 kW × 2), water‑cooled synchronous motor with timing belt + gear. Both run on standard industrial three‑phase power (voltage customizable). The machine size is about 3.2 m long × 2.2 m wide × 2.1 m high.

A: Yes. You must crush the material to a uniform size (around 6 mm) and adjust moisture to 12–18%. Too wet, and the pellets won’t hold together; too dry, and the lignin won’t bind properly. Our ZZCHRYSO pellet line can include a hammer mill and dryer before the pelletizer.

A: Daily: check ring die and roller wear, clean magnets (metal debris), lubricate bearings and drive chains. Weekly: inspect belt tension, check die bolts, clean pellet chamber. Monthly: replace worn dies or rollers, calibrate cutter, check electrical connections. The machine is designed for easy access to wear parts. We provide a full manual and spare parts support.

A: Ideal moisture is 12–15%. If the material is too wet, you’ll need a dryer before the pellet mill. If too dry, add a little water or steam. Our ZZCHRYSO system can integrate a rotary drum dryer to achieve the correct moisture consistently.

A: Biomass pellet plants, sawmills (processing their own waste), furniture factories, farms (straw and corn stalks), power stations, and industrial boiler users. Any operation that needs to turn waste biomass into a sellable fuel.

A: Absolutely. We supply crushing (wood chipper, shredder), drying (rotary drum dryer), pelletizing (this machine), and packaging units. The whole line can be automated with conveyors between stages. Contact our engineers to design a line for your raw materials and output target.
