Testing belt conveyor resistance to motion in

The results of research into the resistance to motion of a single carrying idler set are presented. The measuring system enabled determination of the loading of the tested idler set in the whole range of belt conveyor capacity. Owing to this fact, the dependence between the motion resistance of a single carrying idler set and the mass capacity was determined. The degree of belt conveyor loading was found to have a significant impact on the values of motion resistances
