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;
بیشترAbstract 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).
بیشترChrome Iron Ball Ball Grinding High Chrome 20-150mm Steel Cast Iron Grinding Media Ball For Gold Ore Mining Industry $1,300.00-$1,550.00 / Ton 1 Ton (Min. Order)
بیشترFor Dry grinding, it has the advantages of reducing consumption, saving the ball and increasing efficiency, and for wet grinding ore (bauxite, gold ore, copper ore, iron ore, etc.), the wear resistance of medium-high chromium grinding ball in use is 8 ~ 10 times higher than that of ordinary steel ball, and corrosion resistance.
بیشترThe surface of the cast grinding steel ball is not allowed to have the casting defects such as the crack, and the obvious gas porosity, inclusion, shrinking cavity, cold shut, elephant skin, etc.. It is not allowed to have the shrinkage cavity, shrinking porosity, gas porosity, inclusion, and other cavity defects on the section including plane pasting through the pouring gate and the ball centre.
بیشترThe heat treatment process of high chromium cast iron grinding ball includes wind quenching, oil quenching, and special quenching solution treatment. After repeated test and mining, the oil quenching can fully meet all its technical specifications The consumption of iron ore is twice that of iron ore. The heat treatment process is the use of ...
بیشترGranite grinding tests, under dry and wet conditions, were performed to assess the influence of abrasive particle size to the wear behavior of martensitic high-chromium white cast iron mill balls.
