Measuring the electric or energy power consumption should be related to the production rate or wheat ground. Thus the better flour mill is the one

MoreA grinding power model has been developed to predict the power draw of Outotec’s vertical fine grinding mill (HIGmill). The model is based on a combination of laboratory, pilot and full-scale measurements taken over a range of process conditions. The power draw of the mill is influenced by a variety of factors, ranging from simple
