The main purpose of wrapping the drum with rubber is to effectively change the operating state of the conveyor system, protect the iron drum from being worn out, prevent the occurrence of low friction and slippage of the conveyor belt, and ensure the synchronous operation of the conveyor drum and the conveyor belt. The main diameters of the rubber drum are selected as follows: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, and 89mm. Roller material selection: Carbon steel galvanized, carbon steel coated with glue, aluminum alloy, stainless steel. Type selection of rubber roller: non powered roller, single chain roller, double chain roller, "O" belt roller, conical roller, diamond groove roller.



There are two main types of chain wheel rubber coated rollers: one is single chain wheel rubber coated rollers, and the other is double chain rubber coated rollers
The surface treatment is encapsulation, and polyurethane is the primary consideration for encapsulation materials because polyurethane has excellent elasticity and wear resistance. In addition, natural materials such as nitrile, ethylene propylene diene monomer, etc. can make transportation quieter.
