A misaligned Skid Mounted Belt Feeder will cause the belt to run-off to one side. The belt will tend to creep to the side that first makes contact with the idler roll. This condition can usually be corrected by adjusting a few idlers to change the contact points.
If one section of a belt runs true and another section runs out of line, either the belt is bowed from improper storage or handling or the belt is not properly spliced. If the belt runs out of line consistently at one point of the conveyor, the condition can be attributed to misaligned idlers. Usually the idlers that require adjustment will be located upstream of the point at which the belt runs out of line.
Proper alignment is achieved by loosening the mounting bolts on several idlers on the upstream side and skewing them slightly. When one side of an idler is shifted ahead of the other, the belt shifts to the side that is behind. See fig 1 for a visual description. Re-tighten the mounting boltsbefore restarting the conveyor.
The return side should be adjusted first, starting at the head end. Note the run-off point and adjust a few of the proceeding idlers. The adjustments are made by shifting the idlers so that the belt contacts the roll opposite the run-off.
