Use of Flow Control on Car Dumpers - A Case of Success at Vale

Bruno Eduardo Lopes, Luis Freitas Coutinho

Abstract

The flow control of the car dumper (VV, in Portuguese) used to be done in open loop, i.e., operators used to manually adjust the speed of the feeders (AL, in Portuguese) to make the actual flow equal to the desired flow. The problem was that these manual adjustments were not always performed properly and the result was a loss in productivity and the occurrence of overflow on the feeders. This work demonstrates the techniques of control, modelling and identification used for the implementation of flow control in closed loop in the car dumpers at the Ponta da Madeira Maritime Terminal, Vale.
