Hand ballast screening equipment plays a critical role in crushing and sand-making production lines, ensuring efficient separation of aggregates by size. This equipment is widely used in railway ballast, concrete aggregates, and road base material production.
A typical production line includes:
1. Primary Crusher: Jaw crusher (e.g., Feed size: ≤1200mm, Capacity: 50-1500t/h)
2. Secondary Crusher: Cone crusher (e.g., Output: 20-300mm, Capacity: 60-800t/h)
3. Sand Maker: VSI crusher (e.g., Max feed: 50mm, Capacity: 60-650t/h)
4. Screening Equipment: Vibrating screen (e.g., Deck: 1-4 layers, Mesh size: 3-100mm)
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE750×1060 | 110-320 | 110 |
| Cone Crusher | HPT300 | 90-350 | 315 |
| Screening Machine | 3YK3070 | 70-500 | 37×2 |
Hand ballast screens use multi-layer vibration to classify materials precisely. Key features include high-frequency vibration motors, wear-resistant mesh panels, and modular designs for easy maintenance. Adjustable amplitude (5-10mm) and inclination angle (15°-25°) enhance screening efficiency.
