What is a Wood Chip Hammer Mill?
A hammer mill for wood chips can flexibly adjust the size of the final product between 0.5mm and 20mm by replacing the screens with different apertures, meeting the needs from coarse sawdust to fine wood powder. The flexible screen size allows for customization based on customer needs. Furthermore, if maintenance is required due to long-term use, two workers can easily replace the screen in 10 minutes.
It has a wide range of applications, including wood processing, biomass pellet processing, animal feed ingredients, and various grain processing. It is particularly suitable for efficiently grinding biomass materials and agricultural by-products, primarily serving clients in lumber mills, feed mills, and agricultural processing.
RICHI’s wood hammer mill, also known as a wood chip pellet hammer mill, boasts a robust structure and stable performance, earning it a strong reputation in the industry. For example, a machine we installed at a wood processing plant in Indonesia has been operating continuously for three years, processing an average of 6-8 tons of wood chips daily with minimal major repairs.
Many of our customers use this type of machine, some for over a decade. We always strive for efficient and economical grinding processes, so during the design phase, we specifically equipped the machine with a high-precision dynamically balanced rotor. This reduces vibration and noise during operation, significantly improving the workshop’s working environment.
In addition, the machine’s removable operating door and integrated screen-pressing mechanism make maintenance extremely convenient, demonstrating its user-friendly design. Safety is also a priority, with the machine equipped with a safety interlock to ensure operator safety.
How the Wood Chip Hammer Mill Works
The core function of an electric wood hammer mill is to pulverize material into fine powder. The screen size can be customized to meet your production needs — if you need to adjust the finished product size, simply replace the screen; it’s that simple.
- When the machine is in operation, raw materials enter the pulverizing chamber through the feed inlet. The high-speed rotor drives the hammers, which powerfully impact, shock, and shear the material, rapidly pulverizing it.
- Furthermore, the pulverizing chamber features an advanced teardrop-shaped design and is equipped with a secondary pulverizing mechanism, making it far more efficient than conventional pulverizers.
- We have also added a patented shaft-end air intake system. This system directs a large amount of air into the pulverizing area, further increasing output by over 20%, especially when using small-aperture screens.
- To ensure stable operation, the mill is equipped with a high-precision dynamically balanced rotor to effectively reduce vibration and noise, ensuring smooth operation.
- Furthermore, the mill is equipped with an adjustable screen plate and a material retaining device to effectively break up the material’s circulation layer, ensuring more uniform pulverization and finer size. Furthermore, the rotor can rotate forward and backward, extending the life of the hammers.
- We’ve simplified maintenance and operation. The hammer mill for wood pellets features a removable operator door and an integrated screen press, making screen replacement and equipment cleaning less time-consuming and labor-intensive.
Advantages of the Wood Chip Hammer Mill
A small hammer mill for wood chip is a machine that crushes wood, branches, planks, and agricultural waste into fine pellets or powder. It is widely used in biomass fuel production, wood pellet plants, wood processing plants, and feed processing plants.
Its rational structure, stable operation, and simple maintenance make it an ideal choice for small, medium, and large wood pellet factory.
Efficient Production Process
We’ve designed an advanced teardrop-shaped crushing chamber, coupled with secondary crushing. Compared to standard hammer crushers on the market, this crusher increases output by approximately 25%, making production more efficient in your workshop.
Intelligent Foreign Object Removal
This crusher’s vibrating impactor is intelligent: it automatically avoids any foreign objects that might enter the machine. You don’t need to stop the machine to manually remove small debris, which reduces the risk of equipment damage and unexpected malfunctions caused by small debris.
High Energy Efficiency
We’ve optimized the design of the crushing system. The most significant benefit is that the operating current fluctuation is only 10%, making it more stable than previous models, maximizing energy utilization and reducing long-term electricity costs.
Excellent Fine Grinding Performance
For fine grinding, it features an extra-wide crushing surface, precisely positioned hammer heads, an adjustable screen, and a material retaining device. Material circulates fully within the crushing chamber, ensuring high-quality, fine powder every time.
Extended Wear Part Life
The rotor can rotate forward or reverse — a small feature that means a lot. This ensures even force on the hammer head, preventing faster wear on one side. This means the hammer head lasts longer and you don’t need to frequently replace wearing parts, saving maintenance time and costs.
Safe and Convenient Design
Safety and ease of use are our top priorities. The machine is equipped with a safety interlock that automatically shuts off power if the access door is opened while the machine is running, ensuring your safety. Furthermore, the operator door is removable and features a linked screen lock mechanism, eliminating the need for complicated steps when replacing the screen or cleaning the machine, making it particularly convenient for daily production.
