Modern mining operations rely on efficient crushing and sand-making production lines to process raw materials into high-quality aggregates. Key equipment includes jaw crushers, cone crushers, impact crushers, vibrating screens, and sand makers. These machines work in tandem to break down large rocks into smaller, uniform particles suitable for construction and industrial use.
Below is a summary of critical equipment parameters:
| Equipment | Model Example | Capacity (t/h) | Power (kW) | Feed Size (mm) | Output Size (mm) |
|——————–|—————|—————-|————|—————-|——————|
| Jaw Crusher | PE-600×900 | 50-120 | 55-75 | ≤500 | 60-150 |
| Cone Crusher | HP300 | 90-250 | 220 | ≤230 | 10-40 |
| Vertical Shaft Impactor (VSI)| VSI-1140 | 60-180 | 250 | ≤50 | 0-5 |
| Vibrating Screen | 3YK1860 | 50-300 | 15 | N/A | Multiple grades |
Q1: What is the ideal moisture content for raw materials?
A: Below 5% to prevent clogging and ensure efficient crushing.
Q2: How often should wear parts be replaced?
A: Depending on abrasiveness, jaw plates last ~500 hours, while VSI rotors may require replacement every 800-1,200 hours.
Q3: Can the line produce both coarse aggregates and fine sand?
A: Yes, by adjusting screen meshes and crusher settings.
A granite processing plant in Texas deployed a three-stage crushing system:
1. Primary crushing with a PE-750×1060 jaw crusher.
2. Secondary crushing via an HP400 cone crusher.
3. Tertiary shaping with a VSI-1263. The output reached 200 t/h of
