South Africa’s mining sector demands robust sand screening equipment to process aggregates efficiently. Modern screening systems integrate vibrating screens, trommels, and dewatering units to handle abrasive materials like silica sand, granite, and basalt.
| Model | Screen Area (m²) | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| VS-1845 | 8 | 150-300 | 15 |
| TTS-2060 | 12 | 400-600 | 22 |
| DWS-1530 | 4.5 | 100-200 | 7.5 |
Typical configurations combine jaw crushers (PE-600×900) with multi-deck screens (3YK1860) for graded sand production. Advanced plants incorporate hydrocyclones for precise particle classification down to 75μm.
Q: What screen mesh sizes suit concrete sand?
A: 3mm-5mm square openings produce optimal concrete sand (Zone II grading).
Q: How to reduce screen blinding?
A: Polyurethane panels with anti-clogging apertures outperform steel mesh in wet conditions.
A 200tph plant achieved 95% screening efficiency using:
– Primary scalping screen (1800×4800mm)
– Secondary fine screen with wash system
– Sand recovery unit producing ASTM C33 compliant material
