Working Principle of wood chip hammer mill
The operating principle of this equipment is simple and efficient, mainly relying on high-speed impact and screening control.
- The wood chips enter the crushing chamber through the feed port. Inside the chamber, the rotor is equipped with multiple sets of hammer blades. Under the effect of high-speed rotation, it continuously exerts intense impact and friction on the materials, gradually breaking down the wood into smaller particles.
- The crushed materials are pushed towards the screen installed at the bottom of the chamber. Only particles that meet the size requirements can smoothly pass through the sieve holes and be discharged, while larger particles will continue to be repeatedly impacted by the hammer blades in the chamber until they reach the set particle size standard.
- By replacing screens with different hole diameters, the size of the finished particles can be flexibly adjusted, ranging from coarse wood chips to fine sawdust, meeting the needs of different production processes.
This continuous and efficient process ensures the uniformity of the particle size distribution and the stability of the output, making the wood chip hammer mill an indispensable key equipment in wood processing and biomass energy production lines.

Application of Wood Chip Hammer Mill in Production Line
The wood hammer mill is a core component in various wood processing and biomass production lines. Its ability to efficiently reduce wood chips, shavings, and sawdust into uniform particles makes it highly versatile across different industries. Take a 4-5tph biomass pellet production line as an example. The entire process flow consists of raw material pre-treatment, crushing, drying, pelletizing, cooling, screening and packaging, etc. Among them, the crushing process directly determines the efficiency and quality of subsequent pellet production.
- Raw Material Preparation – Logs, branches, and wood residues are initially sorted and debarked. Large pieces are cut into manageable sizes for further processing.
- Crushing – The prepared wood chips are fed into the wood chip hammer mill. Here, high-speed hammers break down the material into fine and uniform particles suitable for pelletizing. This stage determines the final pellet quality, as consistent particle size ensures better pellet density, smooth extrusion, and reduced dust.
- Drying – Crushed wood particles are dried to the required moisture content, typically 12–18%, to ensure efficient pellet formation and storage stability.
- Pelletizing – The dried material enters the pellet mill, where it is compressed into cylindrical pellets under high pressure. Uniform particle size from the hammer mill ensures smooth pellet extrusion and prevents blockages.
- Cooling – Newly formed pellets are hot and soft; cooling brings them to ambient temperature, hardening the surface and preventing deformation.
- Screening and Packaging – Finished pellets are screened to remove fines or oversized particles, then packaged for storage or transport.
In this workflow, the wood hammer mill machine is indispensable. It not only reduces raw wood to the proper particle size but also ensures the consistency necessary for high-quality pellet production.

What kind of raw materials can this machine process?
Our machine is highly flexible in design and can handle almost all common wood-based biomass materials, including wood chips, sawdust, shavings, branches, offcuts, and even some hardwoods and forestry waste.
For materials with a higher moisture content (such as oil palm by-products, some broad-leaved woods), as long as an appropriate drying process is combined, they can also be crushed smoothly.
Compared to some low-end shredders on the market, our equipment is more efficient and stable when processing hard woods and high-fiber materials, avoiding blockages and reduced production capacity, thereby reducing operational risks for customers.
Why use a wood chip hammer mill in the pellet production line?
The core requirement of the granulation production line is that the raw material particle size must be uniform and meet the requirements of the granulator’s mold holes. If raw materials that have not been crushed are directly used, it is very likely to cause blockage in the granulator, damage to the mold, or poor pellet formation.
The equipment can efficiently crush large-sized raw materials into the appropriate particle size (the finished product size can be within the range of 0.5mm – 20mm), ensuring the smooth operation of subsequent granulation.
From the perspective of the entire production line, although the crushing process is only at the front end, it directly determines the stability of the production line and the yield of the granular products. It can be said to be a “key equipment with small investment and significant effect”.
How do I choose the right model?
RICHI offers a range of models from 0.5 to 50 t/h, suitable for different raw materials and scale requirements of customers. When choosing the equipment, it is necessary to comprehensively evaluate based on the types of raw materials, moisture content, product requirements, and the overall line configuration.
Our engineering team will provide the most suitable solution according to the actual situation of the customers, avoiding problems of oversized or insufficient size, and truly achieving a match between investment and output.
Besides the hammer mill, what other equipment is needed for a complete pellet line? Can you provide the full solution?
Yes. In addition to the wood chip hammer mill, we can also offer a complete particle production line solution, including chippers, dryers, granulators, coolers, screens, packagers, etc., and we support customized configurations.
Different customers have different requirements: some focus on production capacity, some on the degree of automation, and some pay more attention to the stability of the quality of the finished pellets.
