  • TRANSIENT TIME DETERMINATION AT START UP OF BELT

    time at the start up of a belt conveyor is as short as possible, i.e. the electric motor reaches its rated speed as soon as possible. If the transient time is too long, the electric motor will fail to start due to activation of protection devices (if properly adjusted), otherwise electric motor will burn out.

    The Basics of The Calculations of Conveyor Belt Design ParametersAn Example of Conveyor Belt CalculationsConclusion1. Belt tension: The belt of the conveyor always experience a tensile load due to the rotation of the electric drive, weight of the conveyed materials, and due to the idlers. The belt tension at steady state can be calculated as:Tb = 1.37*f*L*g*[2*mi+ (2*mb + mm)*cos (δ)] + (H*g*mm).eqn.1.1 Where,Tb is in Newton.f = Coefficient of frictionL = Conveyor length in meters.

    For the Start-Up Timer, you only have to set the Preset high enough, longer than the last (farthest upstream) conveyor start-up time, and for the Shut-Down Timer, longer than the first (farthest downstream) conveyor shut-down time. Then you should use comparison instructions to do the individual conveyor start-ups and shut-downs.
