### Theory And Practice For U S Stoneware

The use of lifter bars welded or bolted to the mill cylinder in unlined mills reduces media slippage in mills whose rotational velocity is slow. Lifter bars are recommended when the grinding media charge is below 45 percent of the mill volume. Even with lifter bars, it is not practical to go below a 33 percent media charge.

The material charge is equally important in running an efficient milling operation. If too little material is loaded with the media, it will mostly stay in the voids between the media and the media will just grind against each other. Too little material will cause excessive wear on the media while grinding very inefficiently.
