Black Heat-resistant conveyor belt ST2000 Special Conveyor Belts
1. Concept
The heat-resistant conveyor belt [1] is made of multi-layer rubber
cotton canvas (polyester cotton cloth) or polyester canvas covered
with high-temperature or heat-resistant rubber and bonded together
by high-temperature vulcanization. It is suitable for conveying hot
coke and cement below 175°C. , Slag and hot castings, etc.
Type I: It can withstand test temperature not greater than 100℃,
the highest short-time operating temperature is 150℃, code T1.
Type Ⅱ: It can withstand the test temperature of not more than
125℃, the maximum short-time operating temperature is 170℃, and the
code is T2.
Type Ⅲ: It can withstand the test temperature of not more than
150℃, the highest short-time operating temperature is 200℃, and the
code is T3.
Type IV: Can withstand test temperature not greater than 175℃,
maximum short-time operating temperature 250℃, code T4.
2. Maintenance method
Conveyor belts should be kept clean during use and storage, avoid
direct sunlight or rain and snow, prevent contact with acids,
alkalis, oils, organic solvents and other substances, and be one
meter away from heating devices.
During storage, the warehouse temperature should be kept between
18-40 ℃, and the relative humidity should be kept between 50-80%.
During the storage period, the conveyor belt must be placed in a
roll, and must not be folded. During the storage period, it should
be turned once every season.
Conveyor belts of different types and specifications are not
suitable to be used together, and the joints should preferably be
glued.
The type, structure, specification and number of layers of the
conveyor belt should be selected reasonably according to the
conditions of use.
The running speed of the conveyor belt should generally not be
greater than 2.5 m/s. For materials with large lumps and abrasion
and the use of fixed unloading devices, the speed should be as low
as possible.
The relationship between the diameter of the transmission roller of
the conveyor and the cloth layer of the conveyor belt, the matching
of the transmission roller and the reversing roller, and the
requirements for the groove angle of the idler should be selected
reasonably according to the design requirements of the conveyor.
The feeding direction should follow the running direction of the
conveyor belt. In order to reduce the impact on the conveyor belt
when the material falls, a chute should be used to reduce the
material falling distance; the conveyor belt receiving section
should shorten the distance between the rollers and use the buffer
roller as leakage , The belt conforms to adopt a soft and moderate
baffle to prevent the baffle from being too hard and scratching the
belt surface of the conveyor belt.
