Conveyor Belt Tracking

Belt tracking adjustment may be necessary during the break-in period and normal operation to compensate for belt stretching.

Abrasive belt tension must be properly adjusted before adjusting the tracking. Adjust the belt tracking while the conveyor belt is running at its fastest speed.

Tighten the hex nut (Figure 5, Item B) on the side the belt is drifting towards, and loosen the hex nut on the opposite side. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts.

Note: Adjustment should be made in 1/4 turns of the hex nut. Allow time for the belt to react to the adjustment. Do not over adjust.

Conveyor Belt Tension

Conveyor belt tension adjustment may be necessary during the break in period to compensate for belt stretching.

If the conveyor belt can be stopped by hand pressure applied directly to the top of the conveyor bed, the belt is too loose. Insufficient belt tension will cause slippage of the conveyor belt on the drive roller during sanding operations.

Excessive belt tension can cause tracking problems and result in bent rollers, bent take-up brackets and premature conveyor belt wear.

Adjust the hex nuts (Figure 5, Item B) on both sides of the conveyor to obtain a tight, and equally tensioned, conveyor belt. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts.

Drum Height Control

Drum height is controlled by the height adjustment handle (Figure 5, Item A). Turning the handwheel in a counterclockwise direction lowers the drum.

Turning the height adjustment handwheel one revolution lowers the drum approximately 1/16”.
