Crushing equipment is divided into jaw crusher, gyratory crusher, cone crusher, roller crusher, rotary disc crusher, impact crusher and hammer crusher according to the structure and working principle.
Jaw crusher: It has the characteristics of large crushing ratio, uniform product quality, simple structure, reliable operation, easy maintenance, economical operation cost, etc. Various materials not exceeding 320MPa.
Cone crusher: large crushing ratio, high efficiency, uniform particle size, mostly used for medium and fine crushing of medium hardness rocks.
Impact crusher: It can handle materials with a side length of 100-500mm, and its compressive strength can reach up to 350MPa. It has the characteristics of large crushing ratio, cubic particles after crushing, and uniform particle size. It is widely used in stone crushing in highway engineering. middle.
Hammer crusher: suitable for crushing minerals of various brittle materials. The compressive strength of the material should not exceed 100MPa, and the humidity should not exceed 15%.
Factors to consider when choosing a crusher
When selecting a crusher, the type, hardness, particle size of incoming and outgoing materials, output and construction site of the crushed materials should be fully considered.
1. The hardness of the material
Different types of materials have different hardness. In general, the higher the hardness, the higher the crushing difficulty coefficient. When crushing hard or medium-hard stones, jaw crushing equipment should be used as the primary crushing equipment. When crushing medium-hard or soft stones, cone, counterattack or hammer crushers can be directly used.
