Florida’s limestone quarries demand robust crushing and sand-making solutions to produce high-quality aggregates. A typical production line includes:
1. Primary Jaw Crusher (e.g., PE-600×900, 75kW motor, 50-160t/h capacity)
2. Secondary Cone Crusher (e.g., HPT300, 220kW, 90-260t/h)
3. Tertiary Impact Crusher (VSI6X1263, 315kW, 200-500tph for shaped aggregates)
4. Vibrating Screens (3-4 deck, 15-30° adjustable inclination)
| Equipment | Model | Power | Capacity | Output Size |
|———–|——-|——-|———-|————-|
| Jaw Crusher | PE750×1060 | 110kW | 80-240t/h | 60-140mm |
| Cone Crusher | HST250 | 250kW | 120-360t/h | ≤38mm |
| Sand Maker | VSI5X1145 | 440kW | 250-640t/h | 0-5mm |
Q: What’s the ideal moisture content for limestone crushing?
A: Below 5% to prevent clogging in vertical shaft impactors.
Q: How to reduce dust in limestone processing?
Wet suppression systems or bag filters (99% efficiency) are recommended.
A Florida-based operator achieved 650tph production using:
– Primary: GZD1300×4900 vibrating feeder + PE900×1200 jaw crusher
– Secondary: Two HST315 cone crushers with closed-circuit screening
– Final products: 0-5mm (32%), 5-20mm (45%), 20-40mm (23%)
The plant features automated PLC control and metal detectors for equipment protection.
