Limestone is a massive stone material that is mined by a limestone crushing plant through a limestone crusher. Its main component is calcium carbonate (CaCO3), and it also contains clay, dolomite, magnesium carbonate, iron oxide, silicon oxide and some organic impurities.

The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
