Abandoned stone quarries in Utah present untapped potential for aggregate production. Modern crushing and sand-making technology can transform these sites into profitable operations while meeting strict environmental standards.
A complete production line typically includes:
1. Primary Jaw Crusher (e.g., PE600×900, 75kW motor)
2. Secondary Cone Crusher (e.g., HPT300, 220kW)
3. Tertiary Impact Crusher (e.g., VSI1140, 250-400tph capacity)
4. Vibrating Screens (4-layer, 15-30° adjustable angle)
5. Sand Washer (XS3500, 55kW)
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Feed size: ≤500mm, Discharge: 50-150mm |
| Cone Crusher | Closed-side setting: 6-38mm, Capacity: 80-440t/h |
| VSI Crusher | Max feed size: 50mm, Sand yield: 30-50% |
The three-stage crushing system ensures optimal particle shape for concrete aggregates (5-31.5mm) and manufactured sand (0-5mm). Dust suppression systems maintain airborne particles below OSHA’s permissible exposure limits.
Q: What’s the minimum viable production capacity?
A: Economical operations start at 200tph with ROI in 18-24 months.
Q: How to handle hard basalt common in Utah quarries?
A: Our HPT hydraulic cone crushers with manganese steel liners achieve ≤18% wear rate even with abrasive materials.
A former granite quarry now produces:
– 450tph of road base materials
– 120tph of ASTM C33 compliant concrete sand
– Reduced water usage by 40% with closed
