Laboratory tests of indentation rolling resistance of conveyor belts
Abstract One of the methods for lowering of energy consumption in the drive mechanisms of long horizontal belt conveyors is to reduce belt indentation rolling resistances. These resistances depend on a number of factors: bottom cover properties, bottom cover thickness, belt design, idler diameter, load, speed and frequency at which the belt passes on

The indentation rolling resistance of spherically profiled idler rolls
Abstract The energy loss due to indentation rolling resistance in a conveyor belt system can account for up to 60% of the total power usage. It arises due to an asymmetric pressure distribution as a viscoelastic belt cover is indented by a rigid idler roll. This causes a retarding moment on the idler roll, dependent on the load, speed, idler diameter

Effect of Rolling Deformation on Creep Properties of FeCrAl Alloys
FeCrAl alloy is one of the most promising nuclear fuel claddings among many accident tolerant fuel (ATF) materials due to its excellent oxidation resistance and good mechanical properties. However, the effect of process conditions on the creep properties

Investigation into the effect of common factors on rolling resistance of belt conveyor
Since indentation rolling resistance accounts for the major part of total resistance of belt conveyor, it is important to compute it using a proper method during the design and application study of the belt conveyor.
