How does a scrap metal shredder work?

The working principle of the scrap metal shredder is to use a double-axis design to drive the knife shaft to rotate using a high-torque motor and a gear reducer.

 After the material enters the shredding box, the claw structure will clamp it, and it will be broken into small pieces through tearing, squeezing, and then discharged from the bottom. It is suitable for the processing of a variety of waste materials and is the core equipment for scrap metal processing.

The working process of the scrap metal shredder is as follows:

‌Material enters the silo‌: The material is sent into the shredding chamber of the shredder through a conveyor or an excavator grab.

‌Shearing and shredding‌:

The two knife shafts of the double-axis shredder rotate independently under the drive of independent reducers. The claws on the knife shafts automatically squeeze and compact the materials on the rolling, and the coarse crushing effect of the materials is achieved under the joint shearing action of the two knife shafts.

‌Fragment discharge‌:

The raw materials after shearing and shredding come out at the bottom of the shredder.

Safety and control

Henan Hengju's scrap metal shredders are equipped with safety control systems, such as emergency stop buttons, overload protection devices, etc., to ensure safe operation. In addition, modern shredders use advanced automatic control systems, which can adjust the shear force and the movement speed of the blade according to the type of material and processing requirements.

This equipment is not only suitable for metal shredding, but also can handle various waste materials, such as scrap aluminum alloy, scrap rubber, scrap broken bridge aluminum, scrap tires, scrap furniture and scrap electrical appliances, etc.

The design of Henan Hengju's scrap metal shredder equipment enables it to easily handle various scrap metals and other materials, breaking them into smaller pieces, which not only reduces transportation costs, but also facilitates the subsequent recycling and reuse process. When it is difficult to shred large pieces of raw materials, the knife disc can automatically reverse to realize the self-protection function of the machine.
