Hard rock crushers are essential equipment in mining and quarrying operations, designed to break down large rocks into smaller aggregates for construction and industrial use. These machines offer high efficiency, durability, and low operational costs, making them ideal for demanding applications.
A complete hard rock crushing and sand-making production line typically includes:
1. Primary Jaw Crusher: Handles large feed sizes (up to 1500mm) with high crushing ratios.
2. Secondary Cone Crusher: Provides finer crushing with adjustable discharge settings.
3. Tertiary Impact Crusher/VSI Crusher: Produces cubical-shaped aggregates or artificial sand.
4. Vibrating Screens: Classifies materials into different sizes.
5. Conveyors & Feeders: Ensures smooth material flow.
| Model | Feed Size (mm) | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| JC1200 Jaw Crusher | ≤1000 | 300-800 | 160-220 |
| HPC300 Cone Crusher | ≤350 | 200-500 | 315 |
| VSI-1145 Sand Maker | ≤50 | 100-350 | 400-440 |
Q: What’s the lifespan of hard rock crushers?
A: With proper maintenance, core components can last 5-10 years depending on material abrasiveness.
Q: Can these crushers process granite/basalt?
A: Yes, specially designed models with high-chrome wear parts handle abrasive materials effectively.
Q: What’s the typical installation time?
A: A complete production line requires 15-30 days for foundation work and commissioning.
