The Allis-Chalmers cone crusher remains a benchmark in hard rock crushing for sand and aggregate plants. Known for its robust construction and high reduction ratios, this equipment excels in secondary/tertiary crushing stages, producing cubical aggregates ideal for concrete and asphalt applications.
| Model | Max Feed Size (mm) | Capacity (TPH) | Power (HP) |
|---|---|---|---|
| 36″ Hydrocone | 150 | 100-200 | 125-300 |
| 45″ Hydrocone | 200 | 250-400 | 300-500 |
*Note: Capacities vary based on feed gradation and liner configuration.*
A typical setup pairs an Allis-Chalmers crusher with a primary jaw crusher and vibrating screens. The cone’s hydraulic adjustment system allows real-time CSS tuning to optimize output for sand (0-5mm) or coarse aggregates (10-40mm). Downstream VSI crushers often refine the product further.
Q: How to minimize wear in abrasive conditions?
A: Use manganese liners with XT720 alloy and maintain proper feed distribution.
Q: Can it process recycled concrete?
A: Yes, but pre-screening to remove rebar is critical.
A 45″ Hydrocone processed 350 TPH of limestone, achieving 19:1 reduction ratio. The plant reported 98% uptime with bi-annual liner replacements. Key to success was pairing it with a 6×16’ triple-deck screen for closed-circuit crushing.
For legacy units, OEM manuals provide vital maintenance protocols—lubrication intervals and tramp iron relief settings are particularly critical for longevity.
