The wood crusher machine adopts high speed rotating blades and powerful rotor technology, the rotating speed of the blade can be up to hundreds of revolutions/minute. Through the high-speed pair cutting of the blades, it realizes the impact and crushing of logs, branches and boards, and outputs 3-20 mm uniform wood chips, shavings and sawdust.
It can efficiently process all kinds of wood with a diameter of 1-45 cm, and is compatible with bamboo, corn stalks, sorghum stalks, corn cobs and other agricultural wastes, significantly reducing the volume. It is widely used in the fields of wood recycling, particle board and artificial board factories, paper mills, biomass fuel and new energy.
The small wood shredder has a compact structure with a noise level of less than 75 dB. It is driven by an electric motor or diesel engine for stable operation, easy cleaning and maintenance. It supports the adjustment of knife spacing and screen, and the screen or knife plate can be changed according to demand, so as to realize different particle sizes and capacity standards flexibly.
Highlights of wood crusher machine
- The processing capacity can reach 600-4000 kg/h, and the production capacity is increased by more than 50% compared with the traditional model.
- It can pulverize various diameters of tree trunks, branches and many kinds of agricultural and forestry wastes, with strong compatibility of raw materials and wide range of application.
- 85% of the discharged particle size is ≤ 3 mm, with a comprehensive crushing rate of more than 90%, to ensure uniform and stable particles.
- By changing the combination of knives, you can switch between wood chips (3-20mm), wood powder (≤ 325 mesh) and other finished product specifications.
- Compact body, reasonable layout, smooth operation and low noise, suitable for all-weather continuous operation.
- The whole machine only needs a single motor drive, high energy utilization, the same output can save about 40% of the cost of electricity.
- The rear cover of the upper frame can be opened manually and disassembled by one key, which makes cleaning and maintenance more efficient.


Wood shredder applications and finished product uses
- Fine wood chips can be used directly as pulp or filler for the reuse of paper mill waste.
- Wood chips can be mixed with agricultural waste to make briquettes for use as fuel in industrial boilers or for domestic use.
- Wood fibers are combined with resins and hot-pressed to produce MDF or HDF, which are used in upholstery, cabinetry and flooring substrates.
- Decayed wood chips are used as organic substrate for flower seedlings and soilless cultivation of fruits and vegetables.
- Wood chips are used as medium filler to provide good support and nutrient source for edible mushrooms such as shiitake and enoki mushrooms.
- Wood chips are cracked at high temperature to make biochar, which is used for soil remediation (heavy metal adsorption efficiency up to 85%) and wastewater treatment.
- Sawdust briquettes can be efficiently prepared by using fine wood chips ≤5 mm, which are the primary raw material for the sawdust briquette molding machine. (Related Post: Máquina de briquetas de aserrín | Prensa de briquetas de biomasa>>)


Main structure of wood crushing machine
The wood crusher machine generally contains parts such as feed inlet (can be customized according to different materials), body (casing), pulverizing chamber, knife disc, blade, sieve (different sieve hole sizes), and discharge outlet.
The wood crusher machine can also be equipped with a conveyor belt according to your requirements.
Key wearing parts and maintenance
- Alloy tool set: blade life 800-1200 hours (3 times that of a conventional carbon steel tool). Hammer blade adopts carburizing and quenching process, it can be turned over and used after single-sided wear, and the loss rate is reduced by 40%.
- Dynamic screen: high manganese steel perforated screen plate with impact strength of 500MPa, supporting more than 5000 times of material impact.




How this wood shredding machine works?
The wood is first sent into the crushing room evenly from the feeding port, and is cut into 3-20 mm wood chips and sawdust rapidly by the coordinated cutting and impact of the high-speed rotating cutter plate and blades.
Subsequently, the wood chips with the required fineness are automatically screened by the adjustable screen and discharged evenly through the discharge port, while the substandard materials continue to stay in the crushing bin for secondary processing.
