| Jaw Crusher |
Compression between a fixed jaw and a reciprocating movable jaw |
Coarse run-of-mine feed; commonly up to several hundred millimetres, depending on model |
Primary crushed stone, ore, or recycled concrete |
Primary crushing |
Hard rock, soft rock, ores, concrete, and construction waste |
Simple structure, strong feed acceptance, reliable for abrasive materials, and suitable for mobile plants |
Produces a less uniform product shape; generally requires secondary crushing for fine aggregates |
| Gyratory Crusher |
Continuous compression between a gyrating mantle and a concave shell |
Very large run-of-mine feed, often used for high-capacity mine duty |
High-volume primary product for downstream conveyors and mills |
Primary crushing |
Large-scale hard-rock and metallic-ore applications |
Very high throughput, continuous operation, and good performance with large feed |
High capital cost, large installation footprint, and limited suitability for small plants |
| Cone Crusher |
Compression and interparticle crushing between a rotating mantle and concave |
Secondary or tertiary feed, normally smaller than primary crusher feed |
Controlled aggregate, mineral, or manufactured-sand feed |
Secondary, tertiary, and sometimes quaternary crushing |
Abrasive rock, iron ore, copper ore, granite, basalt, and high-quality aggregates |
Good cubicity, adjustable product size, high reduction efficiency, and strong wear resistance |
Sensitive to tramp metal and excessive fines; requires controlled feed and regular wear-part inspection |
| Horizontal-Shaft Impact Crusher |
Impact from high-speed rotor blow bars against impact aprons |
Small to medium primary or secondary feed, depending on rotor size and design |
Well-shaped aggregate and high-reduction product |
Primary, secondary, or recycling-stage crushing |
Limestone, recycled concrete, asphalt, demolition waste, and moderately hard rock |
High reduction ratio, good particle shape, and effective liberation of materials in recycling |
Blow-bar and apron wear can be significant with highly abrasive or very hard feed |
| Vertical-Shaft Impact Crusher |
Centrifugal acceleration and rock-on-rock or rock-on-metal impact |
Fine or intermediate feed, usually after primary and secondary crushing |
Manufactured sand, cubical aggregate, and shaping product |
Tertiary or quaternary crushing and particle shaping |
Aggregates, quartz, granite, basalt, glass, slag, and some industrial minerals |
Excellent particle shape, controlled fines generation, and useful for manufactured-sand production |
High wear in abrasive applications; performance depends strongly on feed grading and moisture |
| Double-Roll Crusher |
Compression, shearing, and limited tearing between two counter-rotating rolls |
Medium to large feed with a controlled top size |
Relatively uniform product with limited over-crushing |
Primary or secondary crushing |
Coal, limestone, gypsum, salt, clay, and other friable materials |
Low fines generation, compact layout, and adjustable product gap |
Not generally preferred for very hard, highly abrasive, or sticky feed |
| Toothed Roll Crusher |
Low-speed compression, shearing, and tearing through toothed rolls |
Run-of-mine or sized feed containing larger soft lumps |
Controlled-size product with comparatively low fines |
Primary or secondary crushing |
Coal, lignite, potash, phosphate, shale, and other soft to medium-soft materials |
Handles sticky or clay-containing feed better than many impact machines and limits excessive fines |
Tooth wear and reduced capacity may occur with very hard or highly abrasive material |
| Hammer Crusher |
Repeated impact from swinging or fixed hammers against breaker plates or grates |
Small to medium feed, with selected designs accepting larger material |
Fine to medium product, often in a single crushing step |
Primary, secondary, or fine crushing |
Limestone, gypsum, coal, glass, clinker, and other relatively soft materials |
High reduction ratio, compact equipment, and effective fine-size production |
Rapid wear with abrasive feed; moisture and sticky material can reduce performance |
| Mineral Sizer |
Slow-speed compression, shearing, and sizing between toothed rotating shafts |
Large, irregular, and often sticky run-of-mine feed |
Controlled top-size product for conveying or downstream processing |
Primary or secondary sizing and crushing |
Coal, overburden, lignite, oil shale, gypsum, and soft to medium-hard minerals |
Low profile, high feed acceptance, low fines generation, and good handling of wet or sticky material |
Usually unsuitable for very hard, highly abrasive rock and may require careful tooth maintenance |
