One-stage crushing
High-capacity crushing option for limestone and brittle medium-hard materials in aggregate and building-material lines.
Equipment role
The heavy hammer impact crusher is used for brittle mineral materials such as coal, gypsum, alum, brick/tile and limestone. The technical material states that it is suitable for materials with compressive strength up to about 300 MPa and moisture content up to about 15%, subject to engineering confirmation.
Selection basis
Selection starts from material condition and plant target, then moves into machine model, chamber configuration, drive power, foundation, conveyor routing and long-term wear-part planning.
Technical parameters
Representative parameter data is organized for preliminary selection. Final model selection should be confirmed against material test data, feed grading, operating hours and plant layout.
| Selection item | Engineering reference | Why it matters |
|---|---|---|
| Material condition | Brittle mineral feed; avoid unsuitable abrasive or sticky feed | Determines whether hammer impact is appropriate |
| Strength reference | Up to about 300 MPa in technical material | Confirms crushing duty and wear risk |
| Moisture reference | Up to about 15% according to material conditions | Affects blockage, screen plate performance and throughput |
| Wear parts | Hammer head, liner and screen plate | Main consumables for spare-part planning |
| Output adjustment | Screen plate size, hammer quantity and drive arrangement | Controls product size and production stability |
Final selection should be confirmed against material samples and process requirements.
