Core Technology Behind Vibratory Screens
Vibratory screens operate using electromagnetic or mechanical exciters that generate controlled vibrations to stratify materials based on size or density:
- Linear Motion Screens: Ideal for high-capacity applications like coal or ore processing due to their straight-line vibration pattern.
- Circular Motion Screens: Commonly used in aggregate classification thanks to their gyratory movement enhancing material flow.
- High-Frequency Screens: Employ rapid vibrations (up to 7,200 RPM) for fine-particle separation in mineral recovery processes.
Advanced features include:
✔ Polyurethane screen panels (longer lifespan vs wire mesh).
✔ Dust enclosures for hazardous environments (e.g., chemical plants).
✔ IoT-enabled monitoring systems predicting maintenance needs.
