We have a belt conveyor length is approx 420M & lift 20M with fixed tripper of 200TPH carrying sinter. Consumed power calculated is 65KW,motor selected is 90KW with fluid coupling at high speed side. To our surprise, the belt at empty condition is not starting. While starting, the motor is drawing high current in the range of 650amps and getting tripped. All alignment and jamming has been checked for all mechanical components. Further,the motor is rotating with fluid coupling and gearbox input/output shafts when the low speed coupling is decoupled from pulley. Can anybody give any possible reason and the solution. ■
