Determination of rolling resistance of belt conveyors

One of the most important components of a belt conveyor is the conveyor belt itself. The conveyor belt can make up till about 70% of the costs of a conveyor and the rolling resistance associated with the rubber (the indentation rolling resistance) can account for about 50% of the total rolling resistance. The selection procedure of the conveyor belt should therefore be taken seriously.
