  • TESTING OF GRINDING BODIES IN THE BALL MILL

    In 2017, we have published a whole series of articles in which we have described in detail the grinding ball testing procedure. In this article we will briefly list the main points that you should know and work out carefully before starting the tests.. The tests are divided into three types:laboratory tests are done in laboratory small mills.
