A test apparatus to determine friability value has been designed to suit limestone strength characteristics used in cement production. The friability values of barite, marble, limestone and bauxite have been determined and compared with the corresponding Bond work index (W i) and grindability index (G) of these materials. The physico-mechanical properties of the tested materials have also been determined to investigate their effect on friability and grinding.

Apart from chemistry, grindability is also a factor in selecting raw mate-rials. In particular, silica additives containing large-grain quartz are very difficult to grind and can result in hard burning and high fuel con-sumption. If quartz silica is employed it should, preferably, have a nat-ural grain size of less than 301ntt.
