Where, G is another constant. The majority of the kiln feed is limestone, which does not have to be finer than 125 µm. If an argillaceous limestone (cement rock) is used, it may be possible to obtain good burnability at particle sizes considerably coarser than this (since the effective calcite grain size is smaller than the particle size).
