Granite is a high-hardness raw material widely used in construction aggregates. A complete crushing and sand-making production line typically includes jaw crushers, cone crushers, vertical shaft impactors (VSI), vibrating screens, and sand washers. Below is a breakdown of key equipment and their roles:
| Equipment | Model Example | Key Parameters |
|---|---|---|
| Jaw Crusher | PE600×900 | Feed size: 500mm, Capacity: 50-160t/h |
| Cone Crusher | HPT300 | Max feed: 230mm, Output: 70-400t/h |
| VSI Crusher | B9100SE | Throughput: 260-380t/h, Product shape: Cubical |
| Screening Machine | 3YK3070 | Screening layers: 3, Power: 15kW |
1. Primary Crushing: Granite blocks are fed into jaw crushers for coarse reduction.
2. Secondary Crushing: Cone crushers further crush materials to ≤40mm.
3. Sand Making: VSI crushers shape particles into high-quality sand (0-5mm).
4. Screening/Washing: Screens classify aggregates; sand washers remove impurities.
Q1: What’s the granite crushing cost per ton?
A: Typically $1.5-$3/ton, depending on equipment configuration and energy costs.
Q2: How to improve sand yield?
A: Optimize VSI rotor speed (+10% RPM boosts output by ~15%) and control feed size.
