| Question | Jaw crusher | Impact crusher |
|---|---|---|
| Typical role | Often used for primary size reduction. | Often used for secondary or shaping duty, subject to the process. |
| Product shape | Depends on the stage and settings. | May help when a cubical product is required, but must be tested against the feed. |
| Feed and abrasiveness | Selection depends on maximum feed and wear conditions. | Wear and operating cost can change with feed characteristics. |
| Best comparison | Compare the complete flow, target sizes, capacity, wear plan and acceptance result. | |
Questions to answer before selection
- What is the maximum feed size and expected moisture?
- What product sizes and shape requirements apply?
- Is the limestone abrasive or contaminated with hard inclusions?
- What capacity and operating hours are required?
- Which stages, screens, conveyors and dust controls are included?
A responsible recommendation requires the process basis and, for uncertain feed, suitable test or supplier clarification.
