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.

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].

These test methods cover physical testing of quicklime and hydrated lime, and of limestone not otherwise covered in ASTM standards. 2. Note 1: Quicklime and hydrated lime have a high affinity for moisture and carbon dioxide. Caution should be taken to protect both hydrated and quicklime during sampling, storage, and testing (see Practice C50).
