Effect Of The Operating Parameter And Grinding Media. The experimental results showed that the abbott-firestone curve can evaluate the lifter surface topography.The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size.Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate.The.

When the feed rate of the ball mill is increased or the grinding rate is required to be too fine, the service efficiency of the ball mill wear-resistant grinding media ball is in a lower range, thus increasing the power consumption of the ball ...
Read Morein 'Iaboratory mills. The corrosion rate of the media was found to be a function of the mineral in the slurry. For copper ore grinding, the corrosion of white irons was found to be between about 40 and 60 pct of the wear. Corrosion was about 25 to 35 pct of the wear for the same media when grinding iron ores.
