Four shaft shredder machine

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

Product Description

The four-shaft shredder has been designed for a wide array of applications and industries, suitable for shredding solid material such as E-waste, metal, wood, plastic, scrap tires, packaging barrel, pallets, etc. Depending on input material and the following process the shredded material can be used directly or go into the next step of size reduction. It is widely used in industry waste recycling, medical recycling, electronic recycling, pallet recycling, municipal solid waste recycling, plastic recycling, tire recycling, papermaking industry and etc.

Working principle

The four-shaft shredders use a two-axis independent drive so that the production of materials to produce the corresponding pressure, to achieve automatic feeding function, a unique knife shaft structure and a four-corner rotary tool, low-speed high torque in the production process, there will be no winding shaft, or stuck phenomenon of the device, thereby increasing the production efficiency, the device is suitable for all kinds of toughness, high viscosity material crushing.


  • It has the characteristics of low speed, high torque and low noise. It is controlled by PLC. It has the functions of starting, stopping, reversing and overloading automatic reversing.
  • The motor + reducer drives the cutter shaft to achieve the shearing effect of low speed and high torque.
  • Bearing six-fold seal, effective waterproof and dust-proof, prolong the service life of bearings.
  • After tool wear, the repair technology of tool coating and welding is adopted to realize the repeated use of the tool, which greatly reduces the maintenance cost of the tool.
  • Separate box design, can easily and quickly remove the entire axle (axle, blade, bearing, sealing system)..
  • Tools are arranged according to helix to achieve high efficiency cutting.
  • . Both the inner hole and the spindle face of the cutter are designed in hexagonal form to realize the uniformity of the force exerted on the cutter.
  • According to different materials and product shapes to be torn up, different types of cutters can be selected.
