Limestone crushers are essential in sand and aggregate production lines, transforming raw stone into graded materials for construction. eBay offers various models suitable for small-scale operations or mobile crushing setups.
A complete limestone processing line typically includes:
1. Primary Jaw Crusher (e.g., PE-400×600 with 30-50t/h capacity)
2. Secondary Impact Crusher (e.g., PF-1214 with 70-130t/h output)
3. Vibrating Screen (3YK1548 with 3-layer separation)
4. Belt Conveyor System (B650×15m)
| Model | Feed Size(mm) | Output Size(mm) | Power(kW) |
|---|---|---|---|
| PE-400×600 | 340 | 40-100 | 30 |
| PF-1214 | 350 | 0-20 adjustable | 132 |
| 3YK1548 | – | 5-50 multi-grade | 15 |
Q: Can limestone crushers produce manufactured sand?
A: Yes, when equipped with VSI crushers (like PLS-900) producing 0-5mm sand with <5% needle content.
Q: What’s the minimum setup for a mobile crushing plant?
A: A compact line could consist of:
– Mobile jaw crusher (80t/h)
– Stacking conveyor
– Requires only 1-acre site
A customer replaced old hammer crushers with:
– 2 × PE600×900 jaw crushers
– 1 × PLS-1000 vertical shaft impactor
Resulted in:
• 40% energy reduction
• Final product meeting ASTM C33 specs
• Production increase to 200tph
