high chromium alloyed cast grinding ball for iron ore

Grinding Media Forged Steel Cast Steel Alloyed White Cast ...

the impact resistance of high-chromium white cast iron is greatly affected by heat treatment. Improvement of grinding media has been a slow process. Grinding balls can beevaluated by the user by keeping records of ball consumption and ore tonnage. But this procedure requires long testing times of months or years (Norman, 1948;

Two- and three-body abrasive wear behaviour of different ...

Abstract In this study, the abrasive wear performance of different heat-treated boron alloyed high chromium cast iron ore grinding balls was examined. Laboratory tests were carried out using pin-on-disc and rubber wheel abrasive testers. Three different loads (32.3, 53.7 and 83.7 N) were applied for two-body high stress abrasion tests (on pin-on-disc).
