Dive pulleys are the key components for power transmission. And belt dive pulleys with rubber coating are usually used for transporting the mixture of coal and ore and usually under continuous operation for long time. This requires dive pulley to be highly abrasion resistant,highly stretching resistant and highly tear resistant . Dive pulleys can also be affected by weather if they are working outdoor(like rusting,sludge). And traditional Dive pulleys with rubber coating are easy to be worn down,slipping and damaging the belt which will decrease the conveyor belt load and the equipments need to be changed frequently .

ⅠProduct Structure

Under the driving of roller, the frictional force between the mechanical driving belt and the surface of dive pulley needs increasing to reduce wear between the surface of pulley and conveyor belt when they are slipping past one another, which will provide stable tractive force and prolong service life time of belt and dive pulley. KINGCERA has developed the dive pulley with ceramic –rubber coating on which the corundum ceramic with false compartment is as abrasion resistant layer to increase frictional force on its surface and abrasion resistant rubber polyurethane  as vulcanization layer, both of which are bonded together with imported adhesives of high strength.

Patent NO: ZL2005200521039

   Small dots on the surface increasing  frictional force    Grooves on the bottom increasing bond forces of vulcanizing
