Head pulley and drive pulley should be provided with a rubber coating to increase the adhesion and friction coefficient on the conveyor belt. A plain form of a lagging sheet is generally applied for the pulley to extend its service life and reduce the slippage.
It can be easily and fast installed. The smooth rotation does not clog the drums. The slippage between belts and drums can be reduced, meanwhile, the noise level and vibration could be decreased. What is more, it has a long service life.
