Good afternoon, dear friends!! Do you still remember me? I am break-day ,and I dream to visit Liming Heavy Industry . Now I am on the way to the company . While now, I explain to you some of the company ’s products with a few words! ! First: crusher – crusher is a machine which uses a metal surface to break materials, typically minerals. crusher s are commonly classified by the degree to which they fragment the starting material, with primary crushers handling coarse materials and tertiary and quaternary crusher reducing finer gradations. Typically, crushing stages are followed by milling stages if the materials needs to be further reduced. The following table describes typical uses of commonly used crusher s:
Type  |
Hardness |
Abrasion limit |
Moisture content |
Reduction ratio |
Main use |
|---|---|---|---|---|---|
| jaw crusher | Soft to very hard | No limit | Dry to slightly wet, not sticky | 3/1 to 5/1 | Quarried materials, sand & gravel |
| Gyratory crushers | Soft to very hard | Abrasive | Dry to slightly wet, not sticky | 4/1 to 7/1 | Quarried materials |
| Cone crushers | Medium hard to very hard | Abrasive | Dry or wet, not sticky | 3/1 to 5/1 | Sand & gravel |
| Horizontal shaft impactors | Soft to medium hard | Slightly abrasive | Dry or wet, not sticky | 10/1 to 25/1 | Quarried materials, sand & gravel |
| Vertical shaft impactors (shoe and anvil) | Medium hard to very hard | Slightly abrasive | Dry or wet, not sticky | 6/1 to 8/1 | Sand & gravel |
| Horizontal shaft impactors (autogenous) | Soft to medium hard | No limit | Dry or wet, not sticky | 2/1 to 5/1 | Quarried materials, sand & gravel |
