Wood Grinding Machines
Wood Grinding Machines Overview
Wood grinding machines are the special equipment used to grind wood blocks, wood chips, branches, wood processing leftovers, straw, bamboo, peanut husk and other raw materials into fine wood sawdust.
By means of high-speed rotating cutters and hammers, wood grinding equipment crushes, cuts and grinds materials strongly, and can process different forms of wood into required sawdust or wood powder in one step.
Wood grinder machine is usually applied in the front section of biomass pellet production lines to provide qualified raw materials for the subsequent pelletizing process. It is an indispensable core pretreatment equipment for biomass energy, wood processing, feed production, and other industries.
Models and Specifications of RICHI Wood Grinding Machines
RICHI wood grinding machines mainly include wood hammer mills and integrated chipper-crushers. The wood hammer mill has certain requirements on the size of the incoming materials, which usually need to have a diameter of less than 5 cm.
In contrast, the integrated chipper-crusher has better material compatibility. It integrates both chipping and crushing functions, and can not only process various garden wastes such as branches, trunks and bark, but also crush crop straws such as corn stalks, sorghum stalks, rice straw and bamboo poles. It can also efficiently process wood processing wastes such as wood blocks and leftover materials.

Key Advantages of RICHI Wood Grinding Machines
RICHI wood grinding machines adopt advanced design technology. Core components such as bearings and hammers are made of selected high-quality wear-resistant materials, and are equipped with high-performance main motors from Siemens Bett, ensuring strong and stable crushing performance and an extra-long service life.
Worldwide Cases of RICHI Wood Grinding Machines
RICHI wood grinding machines enjoy a worldwide reputation and have been successfully exported to many countries and regions. Featuring high efficiency, stable operation and excellent grinding performance, our equipment is widely used in wood pellet production lines, animal feed production lines, cat litter production lines, organic fertilizer production lines and other fields, winning high praise from customers at home and abroad.
Wood Grinding Machines in Austria
For the crushing section of a 5 T/H wood pellet production line in Austria, RICHI equipped one 35kW wood chipper and one 75kW wood grinding machine.
The customer’s raw materials are long wood boards and strips. They are first cut into regular wood chips (20–50mm) by the chipper, then ground into fine wood sawdust of 3–5mm.
This provides qualified and stable raw materials for the subsequent pelletizing process, ensuring the quality of the final wood pellets.
Wood Grinder Machine in Kazakhstan
In the 5 T/H sunflower seed meal feed pellet production line in Kazakhstan, the core function of the crusher is to break up agglomerated sunflower seed meal, fully separate the hulls from the attached kernels, and then grind them into fine powder.
This provides uniformly sized raw materials for the batching, mixing and pelletizing processes, ensuring the quality of subsequent production.
Wood Crusher Machine in South Africa
This South African customer purchased one RICHI multi-functional wood crusher, which is used to crush straw for the production of ruminant concentrate, thereby increasing the utilization value of straw.
The RICHI multi-functional wood crusher features low investment and small floor space, making it suitable for customers with limited budgets and small production scales.
In addition, the multi-functionality of this all-in-one machine also reserves room for the customer to potentially enter the biomass energy or other agricultural processing fields in the future.
Wood Grinding Machines in USA
Two large-scale wood grinding machines are configured in this 10 T/H wood pellet production line in the United States.The two wood crusher machines adopt a parallel design.
On the one hand, it can ensure that the capacity of the crushing process reaches 11-12 T/H, guaranteeing the full-load stable operation of the pellet mill. On the other hand, the two wood grinder machines can serve as backups for each other.
When one equipment needs to replace hammers or screens, the other can continue to operate, maintaining the production line capacity at 5-6 T/H and effectively avoiding the production interruption caused by the full-line shutdown.
Wood Crushing Machine in Indonesia
The Indonesian customer chose the RICHI multi-functional wood crusher machine for his 500kg/h cat litter production line.
The customer’s raw materials includes wood sawdust, wood shavings, bamboo, and straw. RICHI multi-functional wood crusher can complete chipping, coarse crushing and fine grinding in one machine, making it capable of processing various raw materials without the need for multiple equipment.
In addition, this all-in-one machine features high cost performance and a small footprint, making it ideal for the layout of small and medium-sized factories.
Wood Crusher for Sale Canada
In the 2–3 T/H wood pellet production line in Canada, the wood grinding machine is positioned after the drying process and before the pelletizing process.
The customer’s raw materials are wood chips and sawdust with a moisture content as high as 50%, so they must be dried first and then crushed. This not only ensures the crusher achieves its designed capacity and crushing efficiency, but also prevents wet materials from sticking to the screen.
In addition, a vibrating screener is installed after drying to separate qualified sawdust (<5mm) and send it directly to the pelletizing bin, while only wood chips and coarse materials are fed into the hammer mill for further grinding.
how to Choose Wood Grinding Machines
If you want to buy wood grinding machines, in addition to focusing on brand and price, you can pay special attention to the following points to choose the most suitable machine:
Material Situation
Clarify your main raw material type (such as dry wood, wet branches, bark, etc.) and the specific size of the raw materials. This directly determines the required feed port size and motor power of the equipment, which is the core premise for model selection.
Finished Product Fineness
Determine the purpose of the crushed wood sawdust (for example, making pellet fuel, cultivating edible fungi, processing wood panels, etc.). Different purposes have different requirements for the fineness of sawdust, and you need to select the appropriate screen aperture according to specific needs.
Production Capacity
Estimate the amount of materials you need to process per hour, and then choose a model with a matching output. This avoids insufficient production capacity affecting production or excessive production capacity causing waste.
