Belt tension can vary depending on the application. As a general guideline, the bottom of
the belt should be taut and running parrallel with the top strand of the belt. However,
some applications may require more or less tension due to varying belt loading and other
operating characteristics. The belt plow should be adjusted to contact the clean side of
the belt, without applying extra tension.
Belt Tracking
1.
Before attempting to track the belt, be sure:
• belt scraper and belt tension counterweights are in place.
• belt tension is near guidelines suggested on page 15.
• feeder is level and true.
• installation has not warped or twisted the frame.
• head and tail pulley are parallel to each other.
• plow is contacting underside, belt is engaged inside guide rollers.
• belt plow blades are adjustable vertically for proper contact to the belt.
2.
Turn on the feeder and observe its tracking line on the head and tail pulleys.
If the belt is drifting toward one side of the feeder, then adjust the telescoper on
either side of the machine (see below).
Telescoper Adjustment
1.
Determine which side of the weighfeeder you want to adjust. Compressing the
telescoper on one side will cause the belt to drift toward that side of the
weighfeeder. Conversely, extending the telescoper will cause the belt to drift away
from that side of the weighfeeder.
2.
Loosen the jam nut.
3.
Turn the adjusting screw in the desired direction. Often, only a small amount of
adjustment (1 turn or less) will be required.
4.
Observe the results of the adjustment and then readjust, if necessary.
As you extend or compress the telescoper, you may be changing the belt
Note:
tension. If belt tension has increased (or decreased) considerably while attempting to
track the belt, then compress (or extend) both telescopers and complete the belt
tracking process again. To avoid this problem, extend one telescoper while
compressing the other to obtain proper belt tracking.
5.
Re-tighten the jam nut located on the telescoper to maintain the new telescoper
position after completing the tracking procedure.
