specified size grades. Crushing is carried out to reduce the size of the 'as quarried' mineral from large blocks (up to a metre across) to a size finer than 20 to 50 mm. This size reduction is carried out in stages, typically with a low size reduction ratio (<6:1) and is characterised by the use of certain types of crushing equipment (Table 1).
