CONVEYOR BELT TRACKING AND CENTERING
ADJUSTMENTS
(See Figure 9)
If tracking or centering problems occur, first check
for unequal tension measurement on the conveyor
belt tension adjusters. Also check for a buildup of top
dressing material under the belt or on the conveyor
belt rollers.
It is very important during the first 10-15 hours of
operation to frequently check the WideSpin 1530 TM
conveyor belt for misalignment. All conveyor belts
have break-in periods to train the conveyor belt to track
properly. During break-in, some irregular movement
can be expected. After the break-in period, only normal
inspection and adjustment will be necessary.
The conveyor belt scraper assembly should be
inspected to insure that the scraper blade is applying
uniform pressure across the belt.
Step 1.
Set each conveyor belt tension adjuster screw
so that 25 mm (1”) of thread is visible behind the nut.
Operate the machine with the hopper empty. If the
belt is not tracking properly, make quarter (1/4) turn
adjustments to one tensioner until the belt tracks
true. It is very important to give the conveyor belt
enough time (minimum of 10 rotations) to move into
its new position after turning the adjuster screws.
When the conveyor belt starts to run true, continue
running (with empty hopper) for fifteen minutes.
Step 2.
Fully load the WideSpin 1530 hopper with top
dressing material and operate the conveyor belt.
It is normal for the conveyor belt to slightly move
from side to side when the hopper is loaded. Check
tracking and make small adjustments if needed.
Both ends of the rear roller should be visible when
the conveyor belt is running true. It is very important
to give the conveyor belt enough time (minimum of
10 rotations per adjustment) to move into its new
position before making any additional adjustments
Step 3.
After this initial conveyor belt break-in and
training period, use the top dresser as instructed
in the manual. Check the conveyor belt after every
load and make small corrective adjustments as
needed After 10 - 15 hours of use the conveyor
belt should be broken-in and tracking correctly.
Step 4.
After extended use, top dressing material
may build up on the front and rear conveyor belt
rollers causing undue tension on the conveyor
belt or cause tracking problems. Clean the rollers
before adjusting the conveyor belt tension. Before
adjusting the belt, check the following:
● Check for a buildup of top dressing material on
the inside of the conveyor belt.
● Check for a buildup of top dressing material on
the idler and drive conveyor belt rollers.
● Look for damaged, worn or loose bearings on the
idler and drive conveyor belt rollers.
● Look for loose, broken or damaged conveyor belt
tension adjusters.
