    Nov 28, 2016 In aligning the kiln by adjusting or cutting the rollers, it is necessary to cut all rollers equally rather than taking all of the cut on one set of rollers. If only one set of rollers is cut to move the kiln in a given direction, and another set of rollers cut to move the kiln in the opposite direction, such action, if continued, would cause various sets of mechanism rollers to work against each other
