Roller character
King
Roller are made from High Density Polyethylene Roller, the
versatility of this material enables us to satisfy a varied
range of uses where other plastic and steel roller have
failed. The injection molding processes also ensure the high
quality and accurate concentricity necessary to carry our
brand name. ¡@
H.D.P.E-Brief
In 1951 the most dramatic chemical development in the postwar period
occurred-Plastics.
Two young chemists, J. Paul Hogan and Robert L. Banks, were experimenting with
catalysts to produce high-performance gasoline additives.
What Hogan and Banks had discovered was a new plastic-crystalline
polypropylene and High-density polyethylene (HDPE). Most plastics of that era
were either brittle or too easily softened by heat. However, crystalline
polypropylene and polyethylene were tough, heat-resistant and relatively
inexpensive to produce.
Comparative Wear Test Results ¡V See results indicate
that steel life will far outlast steel through wear Acid and
alkaline resistant (no rust shell)

• 50% lighter than steel shell rollers
• Lighter in supply transportation and
handling to stores from supplier.
• Lighter in application when loading to
transport into vehicle from stores
and
then to conveyors for installation which
are long and steep in access.
•
When steel rollers fail they can produce sharp
rotating edges, which can cut
and rip conveyor
belts at a very
significant cost, causing unplanned
down time and interruption to coal supply.
In turn, a
cut conveyor belt
traveling at high speed can pose a
significant risk to employees working in
the vicinity
of the operating plant.
