starting material (rock, ore, etc.) and the grinding ball media (balls), the milling process takes place. The milling process occursduring rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product. The design of a ball mill can vary significantly depending on the size of the required mill, the
Grinding Media Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.
plant ball mill's grinding efficiency (Fig. 1). The functional performance parameters "mill grinding rate through the size of interest," and "cumulative mill grinding rates" from both plant and small-scale tests are applied to this task. A plant media sizing methodology, and industrial case studies, are provided. Background
For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.
