With the rapid growth of China's economic construction, all walks of life have achieved rapid development, so more and more waste materials are produced. In order to save energy, reduce pollution, protect the environment and recycle, crushing equipment was born.

There are four kinds of external forces applied to the solid by the crushing equipment in the crushing process: rolling, shearing, impact and grinding. Press rolling is mainly used for coarse and medium crushing, and is suitable for crushing hard materials and large pieces of materials; Shearing is mainly used for fine crushing, which is suitable for crushing ductile materials; Impact is mainly used in medium crushing, fine grinding and ultra-fine grinding, which is suitable for the crushing of brittle materials; Grinding is mainly in fine grinding and ultra-fine grinding, which is suitable for crushing small pieces and fine particles. The actual crushing process is often several external forces acting at the same time.

Crushing equipment has a wide range of applications, which can tear various metal materials, circuit boards and other materials to manageable shapes and sizes.
