These tools, in either straight or ball end configuration, can produce intricate shapes in very hard steel (H>55Rc), quickly and without grinding. However to reach into small features, the length of the tool becomes large enough (length/diameter ratio >5/1) to influence the dimensional tolerances of the machined part due to deflection of the tool.

have not been proven in large commercial scale mills. Because the grinding operation could be viewed through the open end of the SAG mill, it was evident that maximum throughput occurred when the cascading material (for clockwise mill rotation), was hitting the shell at 30o to the right of the vertical diameter (or 5 o'clock).

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

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%.
