Chaeng Rules of thumb for adjusting rotary kiln support rollers

3. Support roller adjustments to raise gear out of the pinion. (1)Always move the rollers in equally on all piers and avoid moving the drive pier only. Moving drive pier only will over time change the centerline of the unite with the support rollers and will cause maintenances issues. (2)Use a 4:1 ratio on the roller to move the desired distance.

"Say a gear is installed, and in theory it should last more than 20 years. But it doesn't." Somewhere down the line, the wrong lubrication is used, or the right lubricant is improperly applied, or there's unavoidable wear and tear. Eventually there's misalignment between the pinion and gear, Justin explains. Something breaks.
