Scale models of mining equipment provide invaluable insights for designing efficient crushing and sand-making production lines. These detailed replicas help engineers visualize layouts, optimize workflows, and select machinery for processing aggregates like granite, basalt, and limestone.
A typical sand and gravel production line includes:
1. Primary Jaw Crusher: Processes raw ore into 150–300mm chunks (e.g., Model JC4430 with 300TPH capacity).
2. Secondary Cone Crusher: Further reduces material to 20–50mm (e.g., Model CC200, 200HP motor).
3. Tertiary Impact Crusher/VSI Sand Maker: Produces 0–5mm fine sand (e.g., Model VSI1145, 400TPH output).
4. Vibrating Screens: Multi-deck screens classify materials (e.g., Model 3YK3070, 50–800t/h processing).
| Equipment | Key Parameter | Value |
|---|---|---|
| Jaw Crusher | Feed Size | ≤750mm |
| Cone Crusher | Closed Side Setting | 6–38mm |
| VSI Crusher | Rotor Speed | 1,500–2,500 RPM |
| Screening Unit | Sieve Layers | 2–4 layers |

Q1: How to minimize dust in sand production?
*A: Install dust suppression systems (e.g., water spray nozzles) at transfer points.*
Q2: What’s the lifespan of crusher wear parts?
*A: Manganese steel jaws last ~500–800 hours; regular inspection is critical.*
Q3: Can a mobile crusher replace stationary plants?
*A: Yes, for short-term projects (<3 years), mobile units reduce infrastructure costs.*
