Modern crushing and sand-making production lines integrate advanced technology to deliver high-efficiency processing of aggregates. Key equipment includes jaw crushers, cone crushers, impact crushers, vertical shaft impactors (VSI), vibrating screens, and sand washers. These machines work synergistically to produce high-quality sand and gravel for construction, road building, and concrete production.
Below is a parameter table for typical sand-making equipment:
| Equipment | Model | Capacity (t/h) | Power (kW) | Feed Size (mm) | Output Size (mm) |
|——————–|————-|—————-|————|—————-|——————|
| Jaw Crusher | PE600×900 | 50-120 | 75 | ≤480 | 65-160 |
| Cone Crusher | HPT300 | 90-250 | 220 | ≤240 | 5-40 |
| VSI Sand Maker | B-9100 | 100-260 | 400 | ≤50 | 0-5 |
| Vibrating Screen | 3YK2160 | 80-500 | 30 | ≤400 | Customizable |
Q1: How to reduce dust in the crushing process?
A: Install dust suppression systems or use water spray nozzles at transfer points. Enclosed conveyors also help minimize dust emission.
Q2: What maintenance is required for VSI crushers?
A: Regularly check wear parts (rotor tips, anvils) and lubricate bearings. Monitor vibration levels to prevent imbalance.
Q3: Can limestone be used for high-grade concrete sand?
A: Yes, but ensure proper grading and washing to remove fine clay particles affecting strength.
A granite processing plant in Vietnam adopted a complete crushing line with a BBD 4772 DP-controlled mill system. The setup included:
– Primary PE750×1060 jaw crusher
– Secondary HST315 cone crusher
– Tertiary VSI1145
