Research of iron ore grinding in a vertical-roller-mill

Mar 15, 2015 Two Swedish magnetite iron ores were comminuted with a pilot scale vertical-roller-mill. In these experiments the mill parameters dam ring height, grinding pressure and separator speed were varied, according to a factorial design of experiments. Thereby it is possible to generate polynomial regression models for each dependent variable.
