Ball Mill Energy-Saving Principle Usually ball mill operates at fixed running speed, and the cylinder speed is determined by belt pulley and gear reduction mechanism (or hydraulic coupling). The rotating speed of ball mill directly affects the movement of steel balls and the grinding process of material.

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 appeared in the early 19th century; 1870 in the grinding mill, based on the development of a uniform size marker rod mill; in 1908 it created a self-mill without grinding media. 30 to 50 years the twentieth century, the United States and Germany have developed a roll bowl mill, roller mill and other vertical type disc pulverizers.

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a ...

Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7–25 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
