Theball millis a tumblingmillthat uses steelballsas the grinding media. The length of the cylindricalshellis usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture tominimize ballcoating, or slurry containing 20–40% water by weight.

Aball millalso known as pebblemillor tumblingmillis a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of themillvolume and itssizedepends on the feed andmill size.

Commercialball sizes10 – 150 mm; Number,sizeand mass of eachball sizedepends onmillload and whether or not the media is being added as the initial charge. For the initial chargin of amill, Coghill and DeVaney (1937) defined theball sizeas a function of the topsizeof the feed, i.e., d↓V = 0.40 K√F dB =ball size…

Ballmilling is asizereduction technique that uses media in a rotating cylindrical chamber tomillmaterials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber.

Aug 10, 2020·Ball millsare a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using aball mill.
