Stone crushing at a rate of 250 tons per hour requires a robust setup, including the right equipment, power supply, and operational planning. Here’s a breakdown of key considerations:

1. Equipment Needed
– Primary Crusher (e.g., Jaw Crusher or Gyratory Crusher)
– Capacity: ~200–300 tons/hour
– Example: PE-750×1060 Jaw Crusher (80–220 tph)
– Secondary Crusher (e.g., Cone Crusher or Impact Crusher)
– Example: HPT300 Cone Crusher (150–350 tph)
– Vibrating Screen (for grading crushed stone into sizes like 0–5mm, 5–20mm, etc.)
– Conveyor Belts & Feeders (to transport material between stages)
2. Power Requirements
– Total power consumption: ~200–400 kW (depending on hardness of stone).
– Example: A 250 tph plant may require:
– Primary crusher: 90–110 kW
– Secondary crusher
*160–250 kW
– Screens & conveyors: 50–100 kW
3. Material Output Sizes
– Common crushed stone sizes:
– 0–5mm (sand substitute)
– 5–20mm (concrete aggregate)
– 20–40mm (road base)
4. Operational Costs
– Fuel/Electricity: ~$15–$30 per hour
– Labor: 2–4 workers per shift (~$20–$50/hour total)
– Maintenance: ~$0.5–$1.5 per ton
5. Estimated Production in 8 Hours
– Daily output: 2,000 tons/day (250 tph × 8 hours).
6. Environmental & Regulatory Considerations
– Dust control via water spray or bag filters.
– Noise reduction measures if near residential areas.
