Automatic Finess Control of Iron Ore Drying-Grinding Plant

Abstract

A drying-grinding syetem in an iron ore pelletizing plant, consisting of 3000KW ball mills, air separators etc, is fully automatically operated by the the computer control system including fineness control of products. An on-line fineness analyser, and remote-controlled vari-speed air separators are developed to perform the project. The paper reports about the operation results of the fineness control system of the plant in the early stage of operation.
