[0002] In the existing technology, roller crusher is one of the most commonly used crushers. It is widely used in crushing medium-hardness materials in industrial sectors such as cement, chemical, electric power, metallurgy, building materials, and refractory materials. Roller crushers are often divided into single-shaft crushers, double-shaft crushers, and multi-shaft crushers.

[0003] At present, the double-shaft crusher adopts the arrangement of double-shaft toothed knife rollers to achieve the purpose of crushing. Due to the complex composition of solid waste materials, they often contain soft or tough materials such as woven bags, clothes or quilts. In the double-shaft crusher, these soft or tough materials are flexible and are not torn or broken by the toothed knife. They are dropped by the double-shaft rollers in the same straight line, so that the material coming out is not fine enough, resulting in the problem of not meeting the requirements of the later processing size. At the same time, when encountering hard objects such as thick steel plates and steel balls, it is easy to cause the machine to jam. It is necessary to stop the machine to clean the materials in the bucket before continuing to use. The operation is cumbersome and inconvenient, and it also brings safety hazards and poor practicality.
