Modern quarry operations rely on efficient crushing and sand-making production lines to transform large rocks into high-quality aggregates. These plants integrate primary crushing, secondary crushing, sand shaping, and screening to meet construction demands for granularity and cleanliness.
1. Primary Jaw Crusher: Processes raw quarry stones (≤1200mm) into coarse aggregates (150-350mm). Example model: JC5460 with a feed opening of 1400×1100mm and capacity of 800-1200t/h.
2. Cone Crusher: Fine-crushing for mid-hardness rocks. HP500 model achieves 390-990t/h output with adjustable discharge size (6-38mm).
3. Vertical Shaft Impact Crusher (VSI): Produces machine-made sand (0-5mm) with cubic particles. RPM: 1500-2000, throughput up to 600t/h.
| Equipment | Key Parameter | Output Range |
|---|---|---|
| Jaw Crusher | Max Feed: 1200mm | 500-1200t/h |
| Cone Crusher | Power: 315kW | 200-1000t/h |
| VSI Crusher | Sand Yield: 85%+ | 300-600t/h |
Q1: How to reduce dust in sand production?
A: Install sealed covers + pulse bag dust collectors (efficiency >99%).
Q2: Optimal moisture content for screening?
A: Maintain below 3% using dewatering screens or air classifiers.
