Predicting the cumulative resistance of idler rolls is vitally important in calculating the belt tension and therefore power requirements of a system, particularly on long overland conveyors where there are typically more than one thousand idler rolls per kilometer of belt. The rotating resistance occurs due to the friction of the rolling ...
Abstract. To study the variation trend of the indentation rolling resistance of a rubber conveyor belt under different environmental temperatures, the sinusoidal compression displacement test was first carried out on the rubber matrix at six temperatures between -20 C and 40 C by a high and low temperature universal testing machine.
The indentation rolling resistance of conveyor belts is an important design consideration for long belt conveyors and can also be important for heavily loaded belt conveyors. Indentation rolling resistance is dependent on the properties of the conveyor belt, including the carcass and bottom cover as well as properties of the belt conveyor ...

2014-3-15belt, and the indentation rolling resistance due to the indentation of the idler rolls into the belt. The indentation rolling resistance of pipe belt conveyors is higher than the indentation rolling resistance of conventional open trough belt conveyors. In case of the latter, it may already form up to 61 of the total rolling resistance 1.

2019-11-27This internal friction - or asymmetrical tension between idler and conveyor belt -consumes energy. Special rubber compounds and belt designs - for instance an additional transverse reinforcement - reduce the indentation and let the belt run easier over the idlers. Such belt types, on long distance conveyors, can save a lot of money.
