Loading
BELT CONVEYOR LOADING
1. Start with a light load and gradually work up
to the load that the conveyor was designed to
handle. Check chutes to see that the material
is being directed onto the center of the belt.
Off-center load will affect belt alignment in
that the belt will run off center. A central load
will maintain belt alignment.
2. The loading point of a belt conveyor is the
critical point. Here the conveyor receives its
major abrasion and practically all of its im-
pact. The ideal condition is to have the
material flow onto the belt at the same speed
and direction of travel as the belt, with a
minimum amount of impact, and to load the
belt on center.
3. Adjust the skirts to prevent side spillage of
material and to keep the load central on the
belt. The maximum distance between
skirtboards customarily is two thirds the width
of a trough belt.
4. The skirt lengths are designed to stop side
spillage. The material should also be at rest
on the belt before it reaches the end of the
skirt. If the material is still tumbling as it
passes the skirt end, the skirts should be
lengthened.
