In the table below, a load of 65 – 100% and a standard conveyor were assumed for the calculations.
For example, if the longitudinal strength of an EP conveyor belt with 4 plies is 500 N/mm, then the desired values can be found in the table at the intersection of the EP125 column and the row corresponding to the 4 plies. The diameters of drums A, B and C will be 400 mm, 320 mm and 250 mm respectively.
