double-shaft shredder

The working principle of the double-shaft shredder is as follows:

Power transmission

Usually, a dual-motor dual-reducer design is adopted. Two high-torque motors provide power. The power is transmitted to the gear reducer through transmission methods such as V-belts. The gear transmission structure inside the reducer greatly reduces the speed and proportionally increases the torque. The power after deceleration and torque increase drives the two shredder main shafts, causing the two main shafts to move and rotate in relative directions.

Material shredding

When the material enters the shredding box through the feeding system, the material is clamped by the claw structure on the knife shaft. The two shafts equipped with blades rotate relative to each other, and the blades interlock with each other. Under the action of the blades, strong shearing force, extrusion force and tearing force are applied to the material. Through the combined action of these forces, the material is torn, cut and squeezed into small pieces. For example, when processing waste tires, the two shafts rotate in opposite directions, and the blades quickly tear the tires into small pieces.

Discharging control

The discharging particle size of the double-shaft shredder can be controlled in many ways. Blades and teeth of different widths, quantities and shapes can be replaced according to different materials and discharging requirements. When the number of claws is increased, the tearing size of the material by the claws becomes smaller; when the number of claws is reduced, the particle size of the output material becomes larger. The gap between the blades on the two shafts can also be adjusted. The smaller the gap, the smaller the particle size of the shredded material.

During the entire working process, some double-shaft shredders are also equipped with hydraulic pushing devices, which can force the material to the rotor to ensure that the material enters the shredding area continuously and stably. In addition, the equipment is usually equipped with mechanical and electrical overload protection devices. When the processed material is too large or too much, the forward and reverse operation and shutdown functions can be used to protect the machine body.
