Vibrating screens are critical in crushing and sand-making lines to classify materials efficiently. Accurate calculation ensures optimal performance and throughput. Key factors include material characteristics (moisture, density), screen deck inclination (15°–25°), and vibration frequency (900–1500 RPM).
| Parameter | Range |
|---|---|
| Deck Size | 1.2m–3.6m width |
| Capacity | 50–800 t/h |
| Motor Power | 5.5–30 kW |
| Aperture Size | 3mm–100mm |
Use layered screens for multi-grade separation (e.g., 0-5mm sand, 5-20mm aggregate). Adjust amplitude (2–8mm) to prevent blinding. For sticky materials, add rubber balls or ultrasonic cleaners.
Q: How to reduce screen clogging?
A: Increase vibration intensity or use polyurethane mesh panels.
Q: What causes premature wear?
A: Excessive feed rate or unbalanced rotors—maintain ≤30% overload margin.
A 200tph line in Vietnam adopted a 3YK3070 vibrating screen (20° incline, 6mm mesh) to achieve 95% screening efficiency for 0-5mm manufactured sand. Post-installation, downtime reduced by 40%.
