Wood shredder machine

The wood shredder is driven independently by two shafts so that during production, the material is correspondingly pressed to achieve the automatic feeding function.

Working principle

Wood shredder, also known as the shear shredder, is specially designed for shredding wood, reducing the size of materials through cutting, tearing, and squeezing. Mainly used in the crushing and recycling of wood, furniture factory scraps, waste furniture, wooden pallets, construction templates, logs, branches, stumps, roots, and other wood materials.

Applicable materials

The wood shredder is mainly used to crush straw bales, straw, wood, and bamboo for recycling.


  • Wood shredder has the characteristics of low speed, high torque, low noise, etc. It adopts PLC control system and can be controlled automatically. It has started, stop, reverse, and overload automatic reverse control functions.
  • The motor + reducer drives the cutter shaft to achieve the cutting effect of low speed and high torque.
  • The bearing has six seals, which are effectively waterproof and dustproof, which prolongs the service life of the bearing.
  • Tool wear repair technology is adopted after the tool is worn to realize multiple reuses of the tool, which greatly reduces the maintenance cost of the tool.
  • Split box design can easily and quickly remove the entire knife shaft (shaft, blade, bearing, sealing system).
  • The tools are arranged in a spiral line to achieve efficient cutting.
  • The inner hole of the tool and the main shaft surface adopt a hexagonal design to achieve uniformity of the force on the tool.
  • Depending on the material and product shape to be shredded, different types of knives can be selected
