Grinding Balls and Other Grinding Media: Key consumables

Jan 25, 2021 GRINDING MEDIA STEEL BALL HARDNESS. For the best performance, steel ball hardness must be consistent from surface to core. The hardness of cast or forged grinding balls is measured on the Rockwell or Brinell Scales. Hardness tests can be performed in conformance with the manufacturer’s specification

Effect of Heat Treatment on the Hardness and Wear of

Oct 02, 2017 The effect quenching and tempering by different regimes on Rockwell hardness and wear processes of grinding balls 50 and 70 mm in diameter made of two melts of chromium-molybdenum cast iron is studied. The heating temperature for quenching is 850, 950, and 1050 C; the tempering temperature is 250, 400, and 600 C. Iron is analyzed in an electron microscope. Diffraction

PRACTICAL HARDNESS TESTING MADE SIMPLE

Brinell Hardness Number is obtained using a perfectly spherical hardened steel ball of 10 mm pressed against the test surface using a static force of 3000 kg (=29.42 kiloNewton) for at least 10 seconds for steel and measuring the diameters of the indentation left on the surface by means of a graduated low power microscope. The result is either
