Conveyor Belt
Using tail pulley for belt
training will cause serious
damage to the belt and
idlers.
Belt Training
Initial installation of the
conveyor belt should ensure
good alignment of pulleys,
troughing and return idlers.
They should be placed at
right angles to the direction of
travel, leveled and centered on
a straight line.
The fi rst movement of the belt
should be slow and intermittent
so that any tendencies of the
belt to run off may be quickly
observed and the belt stopped
before damage occurs.
Initial movement of the belt
will provide indication of where
corrections are required. The
fi rst corrections must be at
points where the belt is in
danger of being damaged.
Once the belt is clear of all
danger points, a sequence
of training operations can be
followed.
The best procedure to use in
starting the training sequence
is to start with the idler closest
to the tail pulley on the return
run and work toward the head
pulley.
Direction of Belt Adjustment
Belt Cleaning
Special care must be exercised
to keep the return rolls and
snub pulleys clean. Buildup
of material on this equipment
has a destructive effect on belt
training which can cause the
belt to run against the structure
and be damaged.
Refer to the belt cleaner
manual included with conveyor
for more information.
1. Idlers should be clear of dirt
and any material.
2. Check conveyor frame for
level.
3. Check to make sure idlers
are square to the direction
of belt travel.
4. Check belt splice for
squareness.
5. Work from idler to idler in
the opposite direction of
belt travel.
6. Shift only one idler at a
time (shifting subsequent
idlers may cause
overcorrection).
7. Make slight adjustments
rather than extreme ones.
8. Wait for at least three belt
revolutions before making
further adjustments.
9. Never adjust pulleys for belt
training. Pulleys should be
kept square to belt travel
and should only be altered
when other methods have
failed.
10. Apply the “steering wheel”
principle to each of the
idlers when making
adjustments.
With the empty belt trained
satisfactorily, good operation
with load is assured.
Disturbances which appear
with load are usually due to
off-center loading or to the
Do not adjust while belt
