Double Shaft Shredder Working Principle

Nowadays the industrial and environmental protection fields are developing rapidly. Therefore the double shaft shredder has become an important equipment. It is often used in waste treatment, recycling and resource recovery. In this paper, we will discuss the working principle of double shaft shredder. And introduce its structure, operation and application.

As a kind of shredding and crushing equipment. Twin-shaft shredder can pass through two rotating spindles. The material will be torn, crushed and sheared. Thus, it is easy to handle and recycle. The basic principle is through two rotating shafts acting on each other. The main shafts are equipped with blades and hook claws. Under the strong interaction force. The materials are continuously torn and crushed. It can efficiently process various types of materials. Double shaft shredder can be divided into three stages: feeding, crushing and discharging. After the material enters into the feeding system of the shredder. The materials will be evenly distributed on the rotating shaft. The knives start to run. The materials are torn and crushed under the interaction. The processed materials are discharged through the discharge port. Blade type and thickness can be set according to customer’s requirement.

The working principle and structural characteristics of double shaft shredder:

Main parts and drive: the main part of the twin-shaft shredder passes through two kinds of spiral arrangement of the spindle. Click through the reducer to reduce the speed. To get more torque. So as to drive the two spindles to move towards each other.
Shredding and shearing: In the working process, the rotor is biting the material through the knife teeth. The material enters into the knife system, through the interaction of shearing and tearing. So as to achieve the effect of shredding materials.
Blade characteristics: blade thickness shredded material fine Chengdu and shredder blade thickness has a direct relationship. The thinner the thickness of the blade, the smaller the size of the shredded material. The more the number of knife teeth. The shorter the length of the shredded material.

According to different areas of application. Twin shaft shredder can be divided into: plastic shredder, metal shredder, tyre shredder, industrial solid waste shredder, domestic waste shredder, wood shredder and so on. It can be widely used for waste plastics, waste rubber, wood and other wastes.
