Introduction
Ceramic Lagging Pulley
Ceramic lagging or lining of a pulley is used in instances where the pulley operates in extremely aggressive conditions.
An example of such a condition is the pulleys on a bucket elevator, where the pulleys operate within the enclosed elevator housing and material cannot be prevented from becoming trapped between pulley shell and belt.
While rubber lagging may assist with belt tracking in this application, the wear rate would be excessive and thus a longer-lasting lagging is essential.
Ceramic lagging offers better wearing properties and thus, in spite of the aggressive environment, an extended lagging ‘life’. Ceramics are however brittle and should large, hard objects be trapped between the belt and pulley, localized areas of the ceramic liner can be cracked and flake off of the pulley. This can result in belt training problems.
