The quality of our heat resistant belts has proved to meet applications for hot sintered ore, hot pellet, hot clinker, hot clinker, hot chemical, fertilizer, hot cement and other hot temperature materials.The heat resistant conveyor belts are most suitable for heat resistance applications where the temperature of transported materials is over 60°C (140°F)

Special Features

Excellent heat resistance and abrasion resistant cover rubber compound.

Recommended to protect conveyor belt from cracking and hardening on its surface by heat.

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

Rubber cover and carcass maintain excellent properties, even at high temperatures.

Features of Each Grade:

Material and Temperature of Belt Surface :

User Information: Surface temperature of the belt varies with the type and size of the material, belt speed and loading rate. With large lumps (e.g. sintered ores, coke) which allow air to circulate, the belt surface would be cooler than the lumps. In the case of powdery or similar materials, such as cements, aluminum, carbon black, there is almost no temperature difference between material and belt surface. 

In order to select a proper heat resistant conveyor belt it is necessary to consider not only the temperature of materials to be conveyed but also surface temperatures of its belts.

  Flame Resistant (FR) Conveyor Belt                                   

When belts are used in places not easily accessible, it is very important that fire risks be eliminated if possible. Two kinds of fire resistant belts are manufactured: one is specially treated natural SBR Rubber and the other one Chloroprene covered belt.

Flame Duration Time : To a flame at 1000±100°C, a belt test specimen of full thickness shall be inserted against flame, and after keeping it burning for 1 minute, take the burner off, then measure the flame duration time of the tested specimen.

Flame Reappearance Test : After 60±10 seconds from when the burner is removed for the flame duration test. air is blown at speed of 1.5 m/sec. with an air blower from the direction shown in the figure to the left. And the test specimen shall be visually inspected for reappearance of flame.

Drum Friction Test : For each test conducted, the belting shall show no sign of flame (sparks or glow not being objectionable), the drum temperature shall not exceed 325°C, and the sample shall part within the 3 hour test period.

  " DARWIN " Synthetic Conveyor belt                                   

All Synthetic fabric conveyor rubber belt is being successfully used in every industry where bulk material handling is required.It is stronger, lighter and gives better performance, thereby reducing cost per ton material conveyed. Incorporated two to six all synthetic plies. 'Darwin Super' conveyor rubber belting has an integrated construction to carry bulk materials in larger quantities over longer distances at high speeds. Special Features The high tenacity and better strength/weight ratio of Synthetic yarns, as compared to Cotton Yarn, led to the development of all synthetic fabrics resulting in belting with better flex/fatigue resistance, much improved impact resistance, unsurpassed longitudinal and transverse flexibility and other following advantages:

Higher Adhesion Levels: All Synthetic fabric reinforced belts have adhesion levels more than double to that of Cotton reinforced Conveyor Belt, resulting in no ply separation even with high contact, making belt travel possible on very small pulley diameters, complete elimination of cover stripping, improved edge wear characteristics, redundancy of breaker construction both on face and edge.

Less Number Of Plies For Same Strength: The extremely high breaking strength of the Synthetic fabric gives stronger individuals plies, making it possible to meet a given individual strength requirement with lesser number of plies as compared to cotton conveyor belt. A reduction in belt thickness enables belt use on much smaller pulley diameters. Longer roll lengths can be supplied due to reduction in belt thickness, which reduces the number of joints on long drive.

Reduced Belt Weight: All Synthetic fabric reinforced conveyor belts have reduced belt weight as compared to its equivalent All-Cotton of Cotton/Nylon construction. It can be easily handled during the installation due to reduced weight and also improves the idler performance and life by reduction of load on them. Lesser power is required to operate the belt due to its lightweight.
 

Higher Impact Resistance: The superior consolidation of the belt, the high adhesion levels and also the intrinsic properties of all Synthetic plies result in a belt having a lot more resistance than conventional belting. This renders the use of breaker construction in belting superfluous of:

• Significant higher adhesion level between cover and carcass, which can only be achieved with a breaker for conventional cotton/nylon thicker covers available for wear/abrasion.

• Inherently higher carcass flexibility.

To The User This Provides: Full width fabric reinforcement. Fabric reinforced edges which provides additional resistance to edge wear. Elimination of peeling away of Top cover from the edges.
