126.96.36.199 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.
Mills and ball mills for use in the mining and cement industries. By current stan dards, girth gears can be as large as 14 meters (46 feet) in diameter, 1.1 meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on the mill structure to pro vide the stiffness.

Aug 28, 2011 Anonymous Poster 1. 4. Re Ball Mill Girth Gear and Pinion Alignment. 08 27 2011 2 07 AM. pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum, the grease marks will show the contact area. the pinion should contact the girth ring near the center of the gears.
Ball Mill Alignment. Proper placing of pinion(s) axis relative to the girth gear (drive wheel) value of clearances between working teeth. Alignment of clutch system, gears, gear boxes and drive motors regarding pinion's and mill axes. Supervision over adjustment procedure carried out by technicians of the Cement Plant (if necessary).
