Limestone grinding mills are essential for producing high-quality sand and aggregates in Tennessee’s construction sector. Key equipment includes Raymond mills (80-325 mesh), vertical roller mills (20-100t/h capacity), and ball mills (0.074-0.4mm output). These systems integrate with jaw crushers (PE-600×900) and impact crushers (PF-1214) to form complete sand-making lines.
| Equipment | Model | Capacity | Power(kW) |
|---|---|---|---|
| Raymond Mill | 4R3216 | 3-8t/h | 37 |
| Vertical Mill | LM170K | 15-50t/h | 315 |
| Screening Machine | YK1860 | 80-150t/h | 18.5 |
Q: What’s the typical limestone feed size?
A: Primary crushed ≤30mm material works best for grinding efficiency.
Q: How to control product fineness?
A: Adjust classifier speed (+/- 15% range) or air volume in closed-circuit systems.
A Nashville-based operator achieved 120TPH production using:
1. PE750×1060 jaw crusher
2. HPT300 cone crusher
3. LM190K vertical mill
Final products met ASTM C33 standards for concrete aggregates with <3% moisture content.
Modern limestone processing lines incorporate dust collectors (99.9% efficiency) and automated control systems, reducing manpower by 40% compared to traditional setups.
