Modern concrete screening equipment plays a pivotal role in aggregate production lines, ensuring efficient separation and grading of crushed materials. Key machines include vibrating screens, trommel screens, and high-frequency screens, designed to handle varying material sizes (0-300mm) with capacities up to 1,500 t/h.
1. Jaw Crusher: Primary crushing for hard rocks (feed size: ≤1,500mm; output: 50-300mm).
2. Cone Crusher: Secondary crushing (adjustable discharge: 10-60mm).
3. VSI Crusher: Tertiary crushing for shaped sand (0-5mm fineness modulus).
4. Vibrating Screen: Multi-layer screening (e.g., 3YK3070, power: 30kW; throughput: 400 t/h).
| Equipment | Model | Capacity (t/h) | Power (kW) | Output Size (mm) |
|——————–|————|—————-|————|——————|
| Jaw Crusher | PE-1200×1500 | 400-800 | 160 | 150-300 |
| VSI Crusher | VSI-1140 | 200-500 | 440 | 0-5 |
| Vibrating Screen | 3YK3070 | 400 | 30 | Customizable |
Q1: How to reduce screen blockage?
A: Use polyurethane panels or spray water for sticky materials.
Q2: What’s the lifespan of screen mesh?
A: Typically 3-12 months, depending on abrasiveness (e.g., granite wears faster than limestone).
Project: A granite quarry in Texas, USA.
Solution: Deployed a 500 t/h line with jaw crusher + cone crusher + VSI + 3YK3070 screen. Achieved 95% screening efficiency and produced ASTM-certified aggregates for local road construction.
