Withstanding Extreme
Wear in Bulk Material
Handling Equipment
Urethane provides greater wear resistance than steel or rubber, with better
cleanability, and can be customized to meet individual specifications
BULK MATERIAL HANDLING equipment for aggregates production can
experience extreme wear, whether
used by quarries or plants for concrete
batching or highway and construction
material processing.
Batchers, bins, chutes, drums, hoppers, turn-heads, dump cones, belt
cleaners and skirting and other handling equipment can experience severe
wear in contact with a variety of coarse
materials, particularly at "hot spots"
where excessive abrasion occurs.
In such cases, the bare structure of
the equipment may not be adequately
wear-resistant and even traditional
steel or rubber protective liners may
insufficiently control the abrasion.
This can pose a risk of costly spillage through holes and gaps, along
with production downtime for repair
and clean-up.
Sheets made from urethane, short
for polyurethane, provide far better
wear resistance than more traditional
options such as rubber or steel, both
AR400 and AR450 plate. Urethanes
are cost-effective, dependable elastomers that combine some of the performance advantages of high-tech metals,
ceramics, and plastics, along with the
resiliency of rubber. Urethanes also
offer significantly less friction than
rubber which helps to reduce wear
in contact with rough materials like

For aggregate applications, sheets
made from urethane provide far better
wear resistance than more traditional
options such as rubber or steel.

The outstanding abrasion resistance
of urethane elastomers has led
to many important bulk material
handling applications.

aggregates and sand, but also improves
equipment cleanability between wet
batches, which enhances productivity.
Now this "tougher than steel" liner
can be made even more durable with
embedded ceramic tiles. It can also be
cut from full sheets of various sizes to
fit the contours and shapes of high contact areas, so it can easily be welded or
bolted to provide extreme wear protection wherever it is required. While such
liners can be cut to fit and installed
onsite, custom liners made to fit more

complex configurations can increase
reliability, simplify installation, and
further reduce production downtime.

The outstanding abrasion resistance of urethane elastomers has
led to many important bulk material
handling applications.
"In plants that handle bulk materials, like concrete ready-mix facilities,
where severe wear is a problem, special
