HARDNESS OF BALL MEDIA IN BALL MILL Grinding

Hello Everybody my question is: in whole the document about technical specifiion of ball charge media of ball mill, it is stated that the hardness of ball media in startup of the plant should be a little lower than ball media in continuous operation (HRC 5358 and HRC 5863 respectively).

Batec Hardness Testing Issues

Balls that are fiveeighths of an inch diameter (16mm) and larger are surface ground flat and parallel. For hardness testing very large and therefore very expensive balls an alternative hardness test method must be used. This alternative method is used for hardness testing balls made of exotic materials that may cost hundreds of dollars a piece.
