    Variables in Ball Mill Operation | Paul O. Abbe®

    The principle of mill operation is the impingement of the solids between pieces of media. The majority of media motion and milling occurs on the surface of the bed of media where the media is cascading. If there are too few solids, then media will strike media with little milling effect but with accelerated wear of the media and mill shell.

    Grinding also increases the total surface area of a given weight of feed, thereby allowing more space for steam condensation during the conditioning process. This results in a higher feed temperature and more water absorption which together, within the time available, increases gelatinization of raw starch.

    Sep 17, 2019 Milling says: Provide enough material for a good machining cut.When the tool must make a scale cut, the effective lift of the cutting edge is reduced. Bear in mind that you do not always reduce machining time when you leave little stock; you may in fact be losing time and money as a result of excessive cutting edge wear.
