Jul 01, 2003· Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.

Feb 15, 2017· The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality. The regulating wheel acts like a brake, controlling the rotational speed and thrufeed rate of the workpeice. An angular-topped workrest blade supports the workpiece as it passes through the grinder between the grinding and regulating wheels.

The grinding circuit is the largest capital investment of your processing plant. Depending on the grindability of your orebody, abrasion will cause a certain amount of deterioration to the steel media and liners in your circuit. The Abrasion test will allow you to quantify this and design accordingly.

Jul 01, 2016· 3. Conclusion. This article aimed to review and discuss the available literature on the wear of grinding media. The consumption of the grinding media represents an expressive part of the grinding operational costs, reaching up to 50% of it. During grinding, a combination of abrasion, corrosion and impact results in wear of grinding media.
