Grinding media balls are the used to crush or grind material cement, mineral, in a mill. Grinding media are the working part of the mills. Grinding Balls are manufactured from High Carbon or Alloy steel after that forged into balls. These Grinding media ball are performed when the ball are load wear out. Then the…
Grinding Media The grinding abrasives commonly used in materials preparation are silicon carbide (SiC), aluminum oxide (Al2O3), emery (Al2O3 - Fe3O4), composite ceramics and diamond. Emery paper is rarely used today in materials preparation due to its low cutting efficiency. SiC is more readily available as waterproof paper than aluminum oxide.
The grinding media load can be determined from the mill diameter and the distance between the top of the load and the top of the mill. To get an accurate number for steel media, the mill must be ground out before a measurement is taken. For AG and SAG mills a grind out would reduce the amount of grinding media since it is composed of coarse ...
