What is the construction principle of a wood crusher?

Wood crusher is an efficient mechanical equipment for processing wood waste, mainly used to convert materials such as wood, bark, straw, and wheat straw into granular or powdered materials for subsequent reuse or treatment. Its working principle is mainly based on the following steps:

Feeding: The wood waste to be processed is fed into the wood crusher through a feeding system, such as a feeding port, conveyor belt, or feeding roller

Cutting: The core part of a wood crusher is the cutting system, which consists of a high-speed rotating rotor and blades fixed on it. When the rotor rotates, the blade will cut the wood waste at a very high speed, breaking it into smaller fragments or particles

Crushing: With the continuous cutting of the blade, the wood waste is gradually crushed into smaller particles. The size of these particles depends on factors such as the sharpness of the blade, the speed of the rotor, and the hardness and humidity of the wood

Screening: The wood particles that have been cut and crushed will enter the screening system. The screening system consists of multiple screens, each with a different aperture, and different mesh sizes can be selected according to needs. When wood particles pass through the sieve, particles that meet the aperture requirements will be screened out, while larger particles will continue to remain on the sieve for further crushing

Discharge: The screened wood particles will be discharged from the discharge port to obtain granular materials that meet the requirements. These materials can be directly used in fields such as biomass energy, pulp production, animal feed, etc., achieving the reuse of wood waste

Construction of Wood Crusher

The wood crusher mainly consists of the following parts:

Body: The body is usually welded from steel plates and has high strength and stiffness to withstand the vibration and impact forces generated during machine operation

Feeding system: The feeding system is responsible for feeding wood waste into the interior of the machine, including feeding ports, conveyor belts, feeding rollers, and other components

Cutting system: The cutting system consists of a rotor, blades, stator, etc., and is the core part of a wood crusher. The rotor drives the blade to rotate at high speed, achieving cutting and crushing of wood waste

Screening system: The screening system consists of multiple screens, which are used to classify the cut wood particles according to different sizes

Electric control system: The electric control system controls and adjusts the feeding speed, cutting speed, etc. of the wood crusher through components such as an electric control box, motor, and button, to ensure the stable operation and efficient production of the machine

When selecting a wood crusher, it is necessary to choose the appropriate model and parameters based on specific production needs and material characteristics. The main selection parameters include:

Power: Select the appropriate power based on processing capacity, wood hardness, crushing requirements, etc., to ensure that the machine can meet production needs

Sieve diameter: Select the appropriate sieve diameter based on the size of wood particles to be screened, in order to achieve screening of particles of different sizes

Blade type: Select the appropriate blade type based on wood hardness and crushing requirements to improve crushing efficiency and particle quality

By understanding the working principle, structure, and parameter selection of a wood crusher, it is possible to better select and use the equipment, improve the utilization rate and production efficiency of wood waste
