3.1 Principles of crushing. The raw materials are quarried in lump size up to 1- 2 m and must be reduced to less than 0.2 mm. This reduction is carried out in two stages, crushing down to 25 mm. because the mill is designed for a feed of that maximum size- and subsequent grinding. Raw materials occur in widely varying forms and a large range of ...
