Conveyor belts are used in all kinds of industrial scenarios
that involve hauling goods or components from one area to another within a
production or manufacturing plant. Unlike other means of transportation,
conveyor belts act as connecting mechanisms between different kinds of
machines, such that items that come out from one machine can be directly and
seamlessly transported to another machine.
Different kinds of jobs require different kinds of conveyor
belts. For example, industries that deal with manufacture of brittle or
breakable products will require a solid base conveyor belt for maximum
stability between machine transportation, whereas industries dealing with heavy
loads such as ore transport or metal production will require very strong mesh
conveyor belts for maximum load bearing capacity.
Regardless of load capacity, our main point of discussion is
high temperature conveyor belt. These are conveyor belts that are qualified for
working at high temperatures; not necessarily working in hot areas, but lifting
and transporting hot items. They are more hardened than regular conveyor belts,
and are generally made of steel with heat resistant coatings.
Heat resistant conveyor belts have high tensile strength and
robust construction that gives them their heat resisting capacity, in addition
to being non-corrosive. Depending on the range of temperatures handled, they
generally come in 3 variants:
HR-T1 Grade
HR stands for heat resistant, and it is the bare minimum
grade required for transport of heated and hot materials. They can resist
temperatures ranging from 257 degrees Fahrenheit to 356 degrees Fahrenheit
approximately. Actual range can be more or less depending on the manufacturer. They
are usually employed in chemical, plastic and paper manufacturing plants to
handle hot chemicals, plastic pellets and paper pulp respectively. They are
also used in normal industries situated in hot areas where the heat comes from
surrounding room temperatures, not from the actual material handled.
SHR-T2 Grade
SHR stands for super heat resistant, and it forms the middle
ground between 3 grades of heat resistant conveyor belts. Their temperature
resistant capacity ranges from 300 degrees Fahrenheit to 400 degrees
Fahrenheit. As they provide better heat resistance than HR-T1 grades, they are
used for handling very hot raw materials such as hot cement powder in its raw
form, hot chemicals, very hot fertilizers and so on, as long as the temperature
of the material on the belt falls between the specified range of the belt.
UHR-T3 Grade
UHR stands for ultra-heat resistant, making it
the top tier variant of heat resistant conveyor belts. Although they have a
standard temperature resistance range of 400 to 500 degree Fahrenheit, many
firms that manufacture conveyor belts can make custom belts with even higher
temperature resistance limits. They
are generally used to transport very hot, often boiling
materials, not directly but kept on top of containers. They can handle any
material that falls between their specific temperature limit they are designed
for. Ultra-heat resistant belts are usually employed in cement industries,
mineral processing industries and chemical manufacturing plants.
