ABSTRACT:
The invention concerns a method which consists in establishing, by modeling, an algorithm which defines a relationship between the filling ratio of a ball mill and the angular positions of the bottom and the top of the mill content as well as of its absorbed power, in measuring, in the mill whereof the filling rate is to be determined, the angular positions of the bottom and the top of the content as well as of its absorbed power and in determining, on the basis of the measurements and algorithm, the filling rate of the mill.
