Crusher Wikipedia, the free encyclopedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. . In a mobile road operation, these crushed rocks are directly combined with concrete and asphalt which are . leads to choking of the crusher and hence is used only for laboratory purposes and not for heavy duty operations.
Jaw crushers are widely used in the crushing of various ores and bulk materials in mining, construction materials, highways, railways and chemical industries.
Impact crusher is mainly used for metallurgy, chemical industry, building materials, water and electricity and other materials that often require relocation operations.
Cone crusher A crushing machine suitable for raw materials in the metallurgy, construction, road construction, chemical and silicate industries.
Hammer crusher is suitable for crushing medium-hard materials such as limestone, slag, coke, coal and other materials in cement, chemical, electric power, metallurgy and other industrial sectors.
The roller crusher is suitable for crushing medium and high hardness materials in metallurgy, building materials, refractory materials and other industrial sectors.
The toothed roller crusher mainly uses special wear-resistant toothed rollers to rotate at high speed to split and crush materials.
