Hardness Testing For Ball Mill Balls

Hardness Number is obtained using a perfectlyspherical hardened steel ball of 10 mm pressed against thetest surface using a static force of 3000 kg (=29.42kiloNewton) for at least 10 seconds for steel and measuringthe diameters of the indentation left on the surface by meansof a graduated low power microscope. The result is eithercalculated using a given formula (see at the end of thissection) or

hardness tests. Hardness testing is conducted by most grinding ball producers, as for constant microstructure hardness correlates directly with abrasive wear resistance, which is important in all milling applications. Large diameter balls such as SAG balls, may exhibit significant hardness gradients either

Feb 01, 2004 Milling tests to assess the wear behaviour of the grinding media were conducted in 0.45 0.45 m batch laboratory-scale ball mill. A ball and charge of 21 kg and 30 kg, respectively, was used. Each of the test balls was marked (for identification purposes) by means of differently oriented shallow notches, 25-mm long and 3-mm wide that were cut
