  • EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

    EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

    Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

    Back to Basics Hammer Milling and Jet Milling

    ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mills internals is less of an issue.
