El Brocal Overland Conveyor: Control System Re-design and Implementation

This case study examines the control system re-design and network modifications implemented by Conveyor Dynamics Inc. on the original El Brocal Overland Conveyor system to resolve problems associated with the conveyor drive torque control during starting, stopping and running conditions. These problems resulted in symptoms including erratic conveyor behavior, belt over tension, drive slip and inability to achieve nameplate capacity.
