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.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Pre-treated silica was prepared by ball milling the mixture of 60˚g precipitated silica, 72˚g TESPT and 480˚g acetone con-tained inside a concealed ball milling container of volume 1242˚cm3 for 48˚h. High amount of TESPT against the silica was added because it is anticipated the cascaded shearing
