In the 1800s, limestone gold processing relied on rudimentary crushing and grinding tools. While modern technology has evolved, the core principle remains: efficient size reduction and separation. Today’s sand and aggregate production lines integrate advanced machinery to optimize output for construction and industrial use.
1. Jaw Crusher: Primary crushing of limestone (Feed size: ≤1200mm, Output: 10-350mm).
2. Impact Crusher: Secondary crushing (Input: ≤800mm, Output: 0-40mm). Ideal for cubical aggregates.
3. Vibrating Screen: Multi-deck screening (Capacity: 50-800t/h, Mesh: 3-100mm).
4. Sand Maker: Produces high-quality artificial sand (Output fineness: 0-5mm).
| Equipment | Power (kW) | Capacity (t/h) |
|---|---|---|
| Jaw Crusher | 55-400 | 50-1500 |
| Impact Crusher | 90-400 | 70-500 |
| Sand Maker | 110-440 | 60-300 |
Q1: How to reduce dust in limestone crushing?
A: Use water spray systems or enclosed conveyors.
Q2: What’s the ideal moisture content for sand making?
A: Below 5% to prevent clogging in VSI crushers.
A quarry in Thailand upgraded to a 200t/h limestone-sand line using jaw + cone crushers + sand maker, achieving 95% passing 5mm sieve with <3% over-sized particles. The ROI was realized within 14 months due to high-demand concrete sand sales.
