Causes of Damaged Pulleys in Coal Handling Plants:

1. Lagging Maintenance Neglect:

Failure to repair or maintain lagging can result in increased wear on the pulley shell.

2. Material Buildup:

Accumulation of coal, debris or other materials below the pulley can increase friction and cause uneven wear. Material buildup can also cause imbalances in the pulley, leading to vibration and premature failure.

3. Improper Maintenance:

Inadequate maintenance practices, such as infrequent inspections, lack of lubrication or failure to address minor issues can contribute to pulley damage over time.
