Crusher machines are used for crushing of a wide variety of materials in the mining, iron and steel, and quarry industries.
The number of crusher types in terms of style and configuration can be more challenging to quantify, as there are lots of ways to customize rock crushers. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer crusher based on impact. However, before you purchase the stone crusher, you should know more about the types, applied material, main use, and other aspects of the crusher machine.
The following table describes typical uses of commonly used crushers:
| Type | Hardness | Abrasion limit | Moisture content | Reduction ratio | Main use |
|---|---|---|---|---|---|
| Jaw crushers | Soft to very hard | No limit | Dry to slightly wet, not sticky | 3/1 to 5/1 | Heavy mining, quarried materials, sand & gravel, recycling |
| Gyratory crushers | Soft to very hard | Abrasive | Dry to slightly wet, not sticky | 4/1 to 7/1 | Heavy mining, quarried materials |
| Cone crushers | Medium hard to very hard | Abrasive | Dry or wet, not sticky | 3/1 to 5/1 | Quarried materials, sand & gravel |
| Compound crusher | Medium hard to very hard | Abrasive | Dry or wet, not sticky | 3/1 to 5/1 | Mine, building materials |
| Vertical shaft impact crusher | Medium hard to very hard | Slightly abrasive | Dry or wet, not sticky | 6/1 to 8/1 | Sand & gravel, recycling |
| Vertical shaft impact crusher (autogenous) | Soft to very hard | No limit | Dry or wet, not sticky | 2/1 to 5/1 | Quarried materials, sand & gravel |
| Mineral sizers | Hard to soft | Abrasive | Dry or wet and sticky | 2/1 to 5/1 | Heavy mining |
| Crusher buckets | Soft to very hard | No limit | Dry or wet and sticky | 3/1 to 5/1 | Heavy mining, quarried materials, sand & gravel, recycling |
