Everything You Need To Know About Four-Shaft Shredder

The four-shaft shredder can meet demanding working requirements, such as high mixing degree of crushed materials, complex crushing conditions, and strict control of discharge particle size. Its advantage is that it can effectively crush large-sized materials and can control the size of the output.

The four-shaft shredder uses different tool structures to cooperate with each other to ensure high cutting efficiency, uniform and easy-to-control material size after crushing; the machine works with very low noise (75-85 decibels), low dust, low energy consumption, and is suitable for crushing various soft and hard materials.

Feed particle size: 100-2800mm
Production capacity: 500-30000kg/h
Applicable materials: metal, plastic, rubber, tires, wood, textiles, waste paper and other domestic waste, industrial waste, medical waste, hazardous waste, etc.

The four-shaft shredder is widely used, especially for industrial waste crushing, electronic waste crushing, medical waste crushing, old books and confidential documents crushing. The shredder series solves the problems of low efficiency and mesh blocking of easily entangled materials. This type of shredder has excellent design, PLC control, high-efficiency transmission system, and easy-to-maintain structural design.

Working principle of four-shaft shredder:

Main shearing method: formed between the edges of adjacent main cutting knife groups.

Secondary shearing method: relative shearing between the edges of adjacent main cutting knife groups and secondary cutting knife groups.

The discharge size of the four-shaft shredder is controlled by the screen. After the material is cut once, the material with a particle size smaller than the screen hole will be discharged from the mesh hole. The material with a size larger than the mesh hole will be returned to the crushing box along the inner surface of the screen for secondary cutting through the guiding action of the main cutting knife and the secondary cutting knife. This cycle continues until the material can be discharged from the screen hole.

Features of four-shaft shredder:

1. The screen controls the discharge, and the discharge particle size is uniform.
2. Four knife shafts work, with large crushing throughput and high efficiency.
3. The bearing is quadruple sealed, effectively waterproof and dustproof, and extends the service life of the bearing.
4. The motor and reducer drive the cutter shaft to achieve a shearing effect with low speed and high torque.
5. The auxiliary cutting tool group has an auxiliary material grabbing function, which is suitable for crushing large materials.
6. Four sets of cutters cut at the same time, and one crushing can meet the requirements of fine material particle size.
7. After the cutter is worn, the most advanced European tool coating and welding repair technology is used to achieve multiple reuse of the cutter, greatly reducing the maintenance cost of the cutter.
8. PLC monitors the flow in real time, and the cutter shaft automatically reverses when the load is overloaded to protect the motor.
