The fragility of ore depends upon its strength. In a crushed product or mining product, the fragile ore degen-erate to a undesirable fine product during blasting, excavation, loading and transportation. Similarly in a crushing and comminution process by crusher, ball mill or rod mill, as the ore of high strength attains to a desired size, the fragile ore degenerates to superfine.

Indiana Limestone (geologically known as the Salem Limestone) is essentially a monomineralic rock con-sisting of the calcium carbonate (CaCO 3) mineral named calcite. The calcite comes from the skeletal material (about 75 percent) that form the framework grains and from the cementing material (about 20 per-cent) that binds the grains together.
To measure grindability, Bond developed 'Bond's Work Index' (BWI), a 'test mill' and a testing procedure for WI. With the help of this we can work out power required to grind a material from a given feed size to a product of given fineness. Other index known as 'Hardgrove Index is also used to scale grindability of materials, particularly coal.

Intergrinding (co-grinding) in classical ball mills (closed system) leads to a broad PSD, which is usually regarded as beneficial, e.g. regarding workability. Nevertheless, above a certain limit the fine limestone has an excessive water adsorbtion and separate grinding (ball mill and mixing equipment) is favoured. 4

The chipping and grinding processes are the basis for understanding rock cutting during TBM excavation in hard rock conditions. The chips are produced when tensile fractures created by adjacent cutters propagate parallel to the tunnel face and coalesce whereas grinding occurs when fractures do not fully propagate through the rock and only fines are generated. Chipping
