One of them is the Hardgrove index, associated mainly with vertical spindle mills and the other is Bond's grindability, associated with tumbling mills [2]. Bond's grindability can be empirically related to the energy required for comminution and thus is useful for the design and selection of crushing and grinding equipment [3].

Raw mill The raw mill is a major energy consumer and should be designed based on the grindability and moisture of the limestone available. The Vertical Roller Mill (VRM) has at least 30% lesser power consumption, than the comparable ball mill system. Hence, for upto medium hard limestone, the VRM should be the first choice.

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.
