Pulley Lagging By Hofmann Engineering & Marketing Pvt. Ltd.

The Conveyor Equipment Manufacturers Association (CEMA) recommends that Ceramic Pulley Lagging be used for all drive pulleys, particularly those in high-tension applications. Non-driving pulleys (especially on the carrying side of the belt) should be lagged in abrasive environments.
Lagging thickness can vary from a few thousandths of an inch, to a thickness of 1 in. to 2 in., says CEMA. A 60-durometer lagging is the standard to ensure the long wear life and traction desired in most applications.
Most often, lagging is attached to the pulley via vulcanizing (preferred in heavy-duty applications). Or, replaceable lagging can be used. The lagging strips are bolted or welded to the face of the pulley and can be easily replaced in the field.
Also growing in popularity is the use of ceramic pulley lagging that is constructed from hundreds of individual ceramic tiles molded into a durable rubber backing. In certain applications, ceramic lagging can significantly increase drive traction.
* Extends the life of key conveyor components.
* May allow a reduction in the size of the required drive, take-up, etc.
* Reduces wear from abrasive materials.
* Cost-effectively prevents belt slippage by increasing the coefficient of friction between the belt and the pulley.
* Creates a self-cleaning action on the pulley surface and prevents the buildup of transported material, water, snow or ice.
