Referring to Fig. 3 the points of measurement for the roller mills are not interpolated by a curve, as all the products of the roller mills result from the same maximum feed size ( − 14 mm respectively − 8 mm). By connecting every single point with the origin, one will find the grindability assigned to every vertical mill test.
