The ball mill experiments show the size reduction versus energy input for 7 series of experiments in which the weight of dolomite was 660, 1320, 1980, 2640, 3300, 3960, and 5420, respectively. The charge was composed of equal portions of 7 +8 and 8 +10 size fractions. The ball load was 455 stainless steel balls one inch in diameter, having a ...
BALL MILL AIM: To determine the size reduction ratio and critical speed by conducting an experiment in a ball mill. THEORY: Ball mill is a tumbling mill (grinder) type size reduction equipment. It has a cylindrical Shell slowly rotating about a horizontal axis and filled to about half of its volume with balls which act as a grinding medium.
A ball mill is a type of grinder used to grind and 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, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

In this experiment the size of coarse sample was reduced using ball mill which involve grinding balls as a tool to grind the sample. After the size has been reduced, the sample will be placed in sieve shaker to determine the size using various size of sieve which are 600 μm, 500 μm, 250 μm, 125 μm and tray bottom.
Finally, all experiments were carried out using two different ball mill sizes in order to study scaleup effects. Fig. 1 Overview on process, sample production, most important parameters and variables of experimental design: *L = timing of lecithin addition, *B = ball size in second grinding step, *S = shear treatment
