Jaw crusher is a kind of stone crusher which is used widely in many industrial departments including mining, smelt metal, building materials, public road, railway, water conservation, chemical industry and so on, and it is also called rock crusher.
Hammer crusher, which is also called hammer mill, is suitable for crushing all kinds of medium hard materials. MININGhammer mill crusher enjoys high popularity with its unique structure.
Impactor breaker also has mobile type which is called mobile stone crusher machine, and the mobile impact crusher can be used in many industries.
The combination crusher is a new generation highly efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
Mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production.
The major types of MININGcone crushers include Rock cone crusher, Hydraulic cone crusher, Rock cone crusher and Secondary cone crusher. All of these have their own unique applied ranges.
