primary mill variable speed conveyor

Tension Control in Conveyors

For any particular conveyor, there will be a certain amount of power required to move its load. The power is developed by an electric motor and then transferred to the conveyor belting via gearboxes and drive pulleys. On longer conveyors, soft starting devices are included such as clutches, fluid couplings or variable motor speed drive controls.
