The mining industry relies heavily on robust crushing and sand-making equipment to produce high-quality aggregates for construction, road building, and concrete production. Key machinery includes:
1. Jaw Crusher: Primary crushing with capacities up to 1,500 t/h (e.g., PE-1200×1500 model).
2. Cone Crusher: Secondary/tertiary crushing (e.g., HP300 with 220 kW motor).
3. Impact Crusher: For shaping aggregates (output: 50–500 t/h).
4. VSI Sand Maker: Produces 0–5mm sand (capacity: 60–520 t/h).
5. Vibrating Screen: Multi-layer screening (e.g., 3YK3070 with 37 kW power).
| Equipment | Model Example | Capacity (t/h) | Power (kW) | Max Feed Size (mm) |
|——————–|—————|—————-|————|——————–|
| Jaw Crusher | PE-900×1200 | 220–450 | 110 | 750 |
| Cone Crusher | HPT300 | 180–360 | 220 | 240 |
| VSI Sand Maker | VSI1140 | 260–520 | 400 | 50 |
Q1: How to reduce dust in sand production?
A: Use closed-loop systems with bag filters or water spray systems.
Q2: What’s the lifespan of crusher wear parts?
A: Typically 500–1,000 hours, depending on material hardness (e.g., granite vs limestone).
Q3: Can recycled concrete be processed?
A: Yes, but pre-screening is required to remove rebar and debris.
