21.03.2014Common idea is that the belt conveyor resistance is more or less constant throughout its regime from starting to running. If it varies with velocity, then it will affect transient velocities during starting compared to the scenario when the resistance is considered almost equal from zero velocity to final velocity.

07.07.2020These studies have mainly focused on the resistance of a belt while running. The resistance between the belt and the rollers accounts for approximately 60% of the total resistance during belt operation [ 5, 7, 14, 15 ]. The elastic modulus of the bottom cover of the belt is also an important factor for running resistance.
