[0002] A multi-stage crusher is a mechanical device used to crush materials into the required particle size. It is usually composed of multiple crushing units, each unit has different crushing functions and capabilities. However, it still has some disadvantages in actual use. For example, due to the hardness, humidity, shape and other characteristics of the crushed material, it is easy to cause unsatisfactory material crushing effect, so the material needs to be screened and crushed for the second time. However, due to the structural limitations of the crusher itself, the material is often transferred to a separate device, such as a vibrating screen or other screening equipment to complete the material, which prolongs the processing flow and reduces the practicality of the multi-stage crusher to a certain extent.
