Crushing and screening equipment is used for crushing and screening materials according to the required particle size of mining machinery and equipment.
The crushing equipment is used to break the stones to different degrees to obtain the granular material with a certain grain type grading.
From the perspective of crushing principle, the crushing equipment has a variety of ways such as extrusion, shear, and impact, etc. According to the different principles, it can be divided into gyratory crusher, jaw crusher, cone crusher, impact crusher and so on. From the perspective of the working section, the stone materials often need to go through the crushing process of coarse crushing, medium crushing and fine crushing to achieve the requirements of different industries for the particle size, and the type of crusher used in different crushing grades is often differentiated.
| Crushing Grade | Feed Size (mm) | Discharge Size (mm) | Crusher Type |
| Coarse Crushing | 1500-500 | 400-125 | Gyratory crusher / Jaw crusher |
| Medium Crushing | 400-125 | 100-50 | Cone crusher / Impact crusher |
| Fine Crushing | 100-50 | 25-5 | Cone crusher / Sand Maker |
The screening equipment is used to independently screen the broken material into various granular products, and can also be used for auxiliary operations such as dehydration and desliming according to different customer needs.
According to different shapes, screening equipment is mainly divided into fixed screen, roller screen, cylinder screen, curved screen and fine screen. According to the different trajectory of the material, the screening equipment can be divided into elliptical vibrating screen, circular vibrating screen, linear vibrating screen and other types. Different types of screening equipment are suitable for different application fields, such as circular vibrating screen and heavy vibrating screen are usually suitable for the screening and classification of large materials, linear vibrating screen and inertial vibrating screen are usually suitable for the classification and dehydration of medium and fine grade materials.
The crushing and screening equipment are mainly applied in the field of stone aggregate, metal mine and solid waste environmental protection.
