Product Details

Portable heavy duty handling Ep fabric heat resistant rubber conveyor belt for sintered ore

Product Description

Our heat resistant conveyor belts have been developed and refined over many years so that they are more

than capable of meeting the demands of even the most extreme conditions, which in some cases can involve

temperatures as high as 400°C.

Industries where our heat resistant conveyor belts are used with great success include the cement industry,

recycling plants, the steel industry, foundries, the chemical industry and the petro-chemical industry.

The properties of heat resistant conveyor belt:

there are three types of conveyor belts available:
• T1 type - *temperature of material up to 150°C
• T2 type - *temperature of material up to 180°C
• T3 type - *temperature of material up to 220°C

Depends on the ambient temperature, grain size and contact duration
Short time peaks in temperature of material possible up to 400°C. For further details please contact us.

Specifications of heat resistant conveyor belt:

The belt carcass of this product is made use of EP fabric with features of high modulus, low shrink, and high

tensile strength at break. Cover rubber is made of EPDM rubber or Chlorobutyl Rubber (CIIR) that has very

good high temperature resistant property. The belt is refined through mixing rubber with high temperature

resistant materials, assembling and vulcanizing.

Special Feature of Each Grade
Grade	Special Features	Belt Surface Temperature
HRT-1	HRT-1grade heat resistant belt is premium quality Styrene Butadiene Rubber (SBR) compound with very good abrasion resistance and heat resistance to handle hot materials up to 200ºC. This Grade belt is highly resistant to variety of heat applications and good service for iron ore, pellets, casting sand, coke and limestone etc.	100ºC~150ºC
HRT-2	HRT-2 grade is IIR (butyl rubber) hot belt compound features excellent heat resistance which is designed to carry hot loads materials with non-cracking property. This belt is most suitable for the materials such as cement products, limestone, clay, slag, etc.	150ºC~180ºC
HRT-3	HRT-3 grade are the highest quality conveyor belt available to maximum heat resistance. Cover rubber is specially formulated ERP(ethylene propylene rubber)to provide extreme heat resistance and ply adhesion for the applications to handle hot cement, clinker, phosphate, hot sintered ore and hot chemical, fertilizer, etc.	200ºC~220ºC

Special features:

1) Excellent heat resistant and abrasion resistant cover rubber compound.

2) Recommended to protect conveyor belt from surface cracking and hardening by heat.

3) Specially heat-treated and dipped fabric to minimize carcass shrinkage by heat ageing.

The physical and mechanical properties after heat resistant experiment can conform

to below requirements:
