VARIABLE SPEED (VFD) MECHANICAL HYDRAULIC VARIABLE

A variable speed drive is normally used to provide a variable delivery based on the process requirements. Under normal operation, the feeder starts slowly and delivers the required starting torque to shear the ore at the shear bar to control the bed depth. IEM designs equipment for a minimum 200% of MFLT (Motor full load running torque) at starting. When the speed has reached desired setting ...
