How to Maintain a Vibrating Screen

In mineral processing, the efficient operation of a vibrating screen directly affects screening accuracy, production efficiency, and equipment lifespan. To ensure long-term stable performance, special attention should be given to the following aspects:

Screen Mesh Management

Regular wear inspection: Enlarged or damaged mesh openings will reduce screening accuracy and should be replaced promptly.
Anti-clogging measures: For wet screening, consider adding high-pressure spray cleaning; for dry screening, it is recommended to use bouncing balls or an ultrasonic cleaning system.

Optimization of Multi-Layer Screening

Proper mesh size configuration: The upper layer’s mesh size is recommended to be 1.5 times that of the lower layer (e.g., upper layer 10 mm, lower layer 6 mm).
Uniform feeding: Avoid uneven loading by using a vibrating feeder or a distribution plate to ensure even material distribution.

Adjustment of Process Parameters

Vibration frequency and amplitude: High frequency with low amplitude is suitable for fine particles; low frequency with high amplitude is suitable for coarse particles.
Control of feed rate: Excessive speed can overload the screen surface, while too slow feeding will reduce throughput.

Equipment Maintenance & Safety

Regular inspection: Check and tighten bolts, lubricate bearings (replace grease every 3,000–5,000 operating hours).
Troubleshooting: If screening efficiency drops, check the mesh condition; abnormal vibration should prompt inspection of the exciter or damping springs.
