Crushing equipment are jaw crusher , cone crusher, gyratory crusher, hammer crusher , roll crusher , impact crusher , impact crusher and so on. Belonging to construction machinery category. Common characteristics: raw materials, construction and other industries broken foundation engineering machinery.

Scope

Jaw crusher and cone crusher is suitable for crushing hard rock blocks very ( compressive strength of 150-250Mpa); gyratory crusher is suitable for crushing hard ( compressive strength at 100MPA above ) and medium hardness ( compressive strength 100MPA or so ) chunks of rock . Hammer crusher is suitable for crushing medium hardness of brittle rock ( ultimate compressive strength in 100MPA below ) ; roll crusher is suitable for crushing medium hardness toughness of rock ( ultimate compressive strength at 70MPA around ) .
The actual selection , you should also consider the following factors depending on the circumstances :
1.The physical properties of the material , such as friability , viscosity , water content and sediment maximum feed size , etc. ;
2.The total production and finished grading requirements , according to select the type and capacity of the crusher ;
3.technical and economic indicators , so that both meet the quality and quantity requirements, easy to operate, reliable , and maximize cost savings.

Crushing action

1 jaw crusher , cone crusher and roll crusher , in order to squeeze the main role ;
2 hammer crusher and impact crusher , etc., to the impact of the main role ;
3 wheel grinding machine and a roll mill , etc., to the role of the main extrusion and milling ;
4 mill, rod mill , vibration mill and jet mill , etc., to grinding and hit the main role .
Under normal circumstances, crushing process using jaw crusher , cone crusher , broken processing using cone crusher, hammer crusher , impact crusher , crushing processing using roller crusher , grinding process using a ball mill , vibration mill , a jet mill or the like . But this is not absolute , and some machinery both for coarse crushing , but also for the broken .
