Dry batch milling tests were performed in a laboratory scale ball mill measuring by cm. The mill specifications are given in Table 1. A constant ball load of 20% was maintained in all the tests with a ratio of for binary and for trinary ball mix.
The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is %. The result shows that the horizontal ball mill able to grind the calcium carbonate to a size of smaller than 100 mesh (149 µm).

An iron powder ball mill is used to grind iron powder directly, as some industries don't require high iron content and prefer coarser iron powder. The iron powder ball mill grinds the iron powder to a certain size, typically 100200 mesh, which can then be used in magnetic separation processes to extract iron powder. The
The Platteville Powder mills were wrecked by an explosion this afternoon, killing three men and badly injuring another. The dead are: Thomas Bass, William Rottiger and Fred Genthe. H. S. Beck, a machinist of Bethlehem, was badly hurt. The cylinder mill exploded first, and this was followed by the two presses, the shock being felt for miles around.
Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
