Basic concepts
1. A crusher is a mechanical device that crushes large-sized solid raw materials to the required size.
2. According to the size of the crushed or processed material, crushers can be classified into coarse crushers, crushers, and ultrafine crushers.
During the crushing process, there are four types of external forces applied to the solid: shearing, impact, crushing, and grinding. Shear is mainly used in coarse crushing and crushing operations, suitable for the crushing or crushing of tough or fibrous materials and large blocks. Impact is mainly used in crushing operations, suitable for the crushing and rolling of brittle materials. It is mainly used in ultra-fine crushing operations, suitable for most properties of materials for ultrafine crushing operations. Grinding is mainly used in ultrafine crushing or large-scale crushing equipment, suitable for further crushing operations after crushing operations.

scope of application
Large crushers are equipment with higher output under the same crushing fineness, mainly suitable for the crushing and processing of mineral products in industries such as metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower, refractory materials, and steel.
micromillEquipment with lower output under the same crushing fineness is mainly suitable for material crushing and processing in industries such as food, chemical, pharmaceutical, greening, environmental sanitation, etc.
The coarse crusher is mainly used for crushing and pretreatment operations in various industries. Its main function is to process materials with larger diameters of 5-10cm and smaller granular materials with diameters of 5-10mm.
Crushers are mainly used for medium fineness crushing operations in various industries. Their function is to process granular materials into medium fineness powders with a required diameter for subsequent processing or as finished products.
Ultra fine pulverizers are mainly used in most industries for ultra fine pulverization operations, which re pulverize the crushed materials to achieve the required material diameter. They are mainly used for the processing of raw materials for * * products.
