Cone Wheel Grinding for Granite: Optimizing Aggregate Production

Granite crushing and sand-making lines rely on robust equipment to produce high-quality aggregates. Cone wheel grinding technology plays a pivotal role in shaping granite particles into precise gradations for construction applications.

Key Equipment in Granite Processing Line

1. Primary Jaw Crusher: Reduces 800-1000mm granite blocks to ≤300mm
– Capacity: 150-500t/h
– Power: 90-315kW

2. Cone Wheel Grinder (Vertical Shaft Impact Crusher):
– Feed size: ≤50mm
– Output: 0-5mm sand (adjustable)
– Throughput: 60-650t/h
– Impeller speed: 1500-3000rpm

3. Vibrating Screen: Multi-layer separation (3-5 decks)

Technical Advantages

The cone wheel grinding system achieves:
– Cubic particle shape (>90%)
– Low powder content (<10%)
– Adjustable fineness modulus (2.4-3.0)
– Wear-resistant alloy components (service life ≥20,000 hours)

Typical Configuration Table

| Equipment Model | Capacity (t/h) | Power (kW) | Output Size |
|—————-|—————|————|————-|
| GJC120 | 120-180 | 132 | ≤40mm |
| VSI1140 | 200-300 | 250 | 0-5mm |
| 3YK3070 | 150-400 | 45 | Multi-grade |

FAQ Section
