    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

    A suitable tool for this method is a planetary ball mill, such as RETSCH’s PM 100, PM 200 or PM 400, which provides the necessary energy input. The common rules for size reduction to micron size do not apply for the nano-scale; with decreasing particle size, electrostatic and even molecular interactions increase, leading to particle

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
