Modern beneficiation plants rely on robust machinery to process raw materials into high-quality aggregates. A typical crushing and sand-making line includes jaw crushers, cone crushers, impact crushers, vibrating screens, and sand washers. These machines work synergistically to produce graded sand and stone aggregates for construction, road building, and concrete production.
Below are key parameters of standard machines:
| Equipment | Model Example | Capacity (t/h) | Power (kW) | Weight (t) |
|——————–|—————|—————-|————|————|
| Jaw Crusher | PE600×900 | 50-120 | 55-75 | 15.5 |
| Cone Crusher | HPT300 | 100-250 | 220 | 26 |
| Vertical Shaft Impactor (VSI)| VSI1140 | 60-180 | 250 | 18 |
| Vibrating Screen | 3YK3072 | 80-150 | 30 | 8.5 |
Q1: How to reduce wear in crushers?
A: Use high-manganese steel liners and maintain proper feed size distribution.
Q2: What’s the ideal moisture content for screening?
A: Below 5% to prevent clogging.
Q3: Can VSI crushers produce shaped aggregates?
A: Yes, they excel in cubic-shaped output for premium concrete mixes.
A limestone project in Vietnam deployed a 200tph line with PE750×1060 jaw crusher + HST315 cone crusher + VSI5X1145 sand maker. The output achieved ISO-certified 0-5mm, 5-10mm, and 10-20mm aggregates with <3% powder content, meeting strict dam construction standards.
For optimal performance, always match equipment to material hardness and target gradation. Regular maintenance ensures longevity—lubricate bearings every 500 hours and inspect wear parts weekly.
