Once again, CCI has the answer in Pulley Lagging
CCI_Lagging is designed to meet the demands of your application. We offer vulcanized rubber, which is baked on the pulleys in an autoclave. And we offer cold bond lagging which is adhered to the pulley surface with indutrial adhesives.
Strip lagging is available in 72" strips. It is welded on the face of the pulley
We also prvide shell lagging which features rubber bonded to rolled shell selection. This product is excellent for installation on the pulley while it is still on the conveyor frame.
Q. When should I put lagging on my pulley?
A. Lagging is used primarily on drive pulleys to increase the coefficient of
friction between the pulley and belt.
Q. What is the benefit of grooving the lagging?
A. Grooved lagging is used primarily to eliminate moisture from the underside
of the belt. It also can aid in traction between the pulley and belt. We
see little, if any, benefit in grooves tracking the belt.
In an aggregate facility, conveyor belt slippage can be a problem. One possible solution is the use of lagging-in a variety of forms-on the conveyor pulley. When applied to a conveyor pulley, lagging material performs two functions. Its primary function is to aid in gripping the conveyor belt, thus helping transmit torque from the drive to the pulley in order to carry the load on the conveyor belt. Lagging also prolongs the wear life of the pulley.
There are several types of lagging used in aggregate facilities. Our lagging is a rubber compound that has been cured in an autoclave . After curing, the lagging is grooved and then shipped to customers.
One potential challenge to this type of system, however, is that when removed from the autoclave, the lagging continues to cure and the durometer or hardness of the rubber will increase. For instance, the measure of the durometer of the lagging material when first taken from the autoclave may be approximately 60, nearly equal to the durometer of the conveyor belt. After several days or weeks, additional curing may significantly increase the lagging's durometer. If the durometer of the lagging exceeds the durometer of the conveyor belt, slippage can occur, causing a new conveyor pulley to slip against the belt.
Aggregate facilities combat slippage by applying more tension to the conveyor belt or by roughening the lagging surface with a hand-held grinder. Chemicals should not be applied to the lagging or belting to improve traction because they can disintegrate the rubber compound over time, making the problem worse.
Strip or slide lagging also is also used by CCI. Like pre-applied lagging, the rubber compound in strip lagging undergoes a similar pressure cured process.
Strip lagging applies easily: retaining strips are welded to the face of a conveyor pulley and the lagging strips slip into the grooves between the retaining strips and the pulleys.
Ceramic lagging is used to combat chronic belt slippage and can provide twice the gripping power of molded rubber lagging. Ceramic lagging costs two to three times more than any of the lagging products previously mentioned and is applied much like the cold vulcanized lagging process.
