Vibrating screens are indispensable screening equipment in crushing and mineral processing lines. Long-term vibration load, dusty environment and uneven feeding easily cause common faults such as screen mesh blocking, abnormal vibration, bearing overheating and side plate cracking. Timely troubleshooting can effectively reduce downtime loss.
Common faults include material accumulation on screen surface caused by excessive humidity, eccentric shaft damage leading to vibration deviation, loose spring support causing body shaking, and bearing lack of lubrication causing high temperature alarm.
Standard troubleshooting steps: Clean screen mesh every shift to prevent fine mud adhesion; regularly check spring elasticity and bolt tightness; replace lubricating grease every one month; adjust feeding uniformity to avoid material concentration on one side; install rubber buffer pads to reduce metal fatigue cracking.
For heavy-duty screening under high-load conditions, high-strength welded side plates and anti-clogging screen mesh are recommended. Polyurethane screen meshes have longer service life than steel meshes in wet and sticky material processing.
A Tanzanian granite quarry optimized screen maintenance procedures, reducing screen failure downtime from 12 hours weekly to less than 3 hours, greatly improving overall production continuity.
