Verfahren zur Herstellung von Trocken-Schuettgut durch Quetschen und Mahlen

The method of controlling a process for the production of dry material on a continuous feed and discharge basis such as, for example, ore pellets, in a mill unit by the crushing, grinding or milling of the dry material is achieved by measuring the amount of material being fed and the amount of process material being discharged to obtain a first signal value and a second signal value, respectively, with each of these two signal values being thereafter fed to a first control means. The degree of fill of the milling unit is electroacoustically detected to obtain a signal value therefor which is thereafter passed to a second control means. The output signal of the second control means is passed to the first control means to adjust same to a constant value. The output signal of the first control means adjusts the first control means so that the first and second signal values of the material being fed and the material being discharged will be substantially equal during the processing of the dry material.
