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.

Land area calculation. Calculating areas of irregular polygons is a non-trivial task without sophisticated surveying instruments. One way to calculate areas of such plots, is to break them into a number of triangular-shaped plots as in image shown below and then find the area of each triangle using Heron's formula and sum them up.
