SPECIAL PRODUCTS: HIGH HEAT RESISTANT

Hamaheat High Heat Belts

50 Years of Research Gets You 750ºF of Performance

For decades plants like yours have been forced to cope with conveyor belts that quickly crack and blister under high heat conditions. The resulting carry-back, clean-up and maintenance costs have been a constant problem.

Finally, a new breed of belt is changing all that.

Over half a century of research and development has produced a belt with advanced construction, providing durability under extreme material temperatures as high as 750ºF (400ºC). The Hamaheat Belt gives you superior abrasion resistance in severe conditions, the lowest cost-per-tonnage and the best ROI in the business.

Breakthroughs in heat tolerance, abrasion resistance and splice adhesion propetrties have been industry-proven throughout the world in cement plants, lime kilns, potash manufacturing, foundries, coke oven plants, iron ore pelletizing and other high heat applications. Shouldn’t you be getting this kind of performance, durability and results from your belt?

Advanced Construction Withstands Heat Up To 750ºF (400ºC)

Hamaheat belts resist hardening and cracking while carrying fine or coarse loads up to 750ºF (400ºC)*. Laboratory tests show that in high-heat conditions Hamaheat belts maintain cover tensile strength almost five times greater than the two leading brands. Improved cover performance under extreme heat extends the life of your belt while minimizing material carry-back. Clean-up and maintenance costs associated with premature cracking & blistering are greatly diminished.

Hamaheat belts resist the cupping and/or curling tendency of typical high-temp belts allowing for better belt tracking and reduced edge damage. All while enhancing the overall safety of your operation.

*Maintaining a belt surface temperature under 400ºF will maximize belt life.

Superior Abrasion Resistance Under Extreme Conditions

In comparison with conventional leading brand high-heat EPDM belts, Hamaheat belts show significantly less cover loss in abrasion tests (DIN 53516). (See graph to right.)

Lowest Cost-per-tonnage and Best ROI

In side-by-side tests with conventional EPDM high-heat belts, Hamaheat belts lasted significantly longer carrying a wide variety of high-heat materials. The Hamaheat advantage gives you greater peace-of-mind and optimum ROI.

Vulcanized Splices Remain Intact For The Life of Your Belt

Hamaheat adhesion values actually increase with heat so you can count on splices to last the life of your belt when properly vulcanized. Hamaheat belts eliminate the need for mechanical splices, allowing you to take advantage of belt cleaners and further reduce the cost cycle associated with carry-back material and clean-up.

Run True With Molded Edges Manufactured To Width

Conventional high-heat belts are often slit from wider rolls. That’s why it’s not uncommon for belts to have some camber, requiring more time to train initially. In contrast, Hamaheat belts are manufactured to width with molded edges so you never get a hooked belt. They’re good to go from the moment they’re installed. And they continue to perform like no other belt on the market.

Extreme-heat Carcass Design

Hamaheat’s extreme heat technology strength starts at the core. The carcass is made from a proprietary fabric and dipping process that resists delamination and flexural fatigue.

“From less downtime and dramatically longer belt life to reliable splices and reduced maintenance hours spent, Hamaheat belts have allowed us to use our resources more efficiently for over five years now. To say that Hamaheat has made a big improvement to our operation would be an understatement.”

“On our most extreme high-heat clinker belts we simply haven’t had anything last as long and perform as well as Hamaheat belts.”

Dennis Davis
Maintenance Planner, CEMEX
 

“Vulcanized splices that last the life of the belt, less wear and tear on the system from carry-back, increased belt life, and savings on maintenance man-hours are the main benefits we have realized using Hamaheat belts.”

Side-by-side Comparison

 
Measures volume loss of cover rubber.Higher number (more volume loss) =less abrasion resistance.
Test methods: 365ºF (180ºC) after168 hours operation.

Elongation/elasticity of cover rubber is important to belt performance and service life. Competitors’ EPDM belts rapidly deteriorate under high temps. Hamaheat’s cover rubbers retain elasticity. Result: maximum performance and service life
Test methods: 365ºF (180ºC) after
168 hours t.
Maintaining tensile strength of over rubber is important to a belt’s performance and service life. Competitors’ EPDM belts quickly weaken under high temps. Not Hamaheat cover rubbers.
Test methods: 365ºF (180ºC) after 168 hours operation
Adhesion from cover to ply and from ply
to ply is critical to extending belt life
and performance. High adhesion ensures splice integrity and resistance to flexural fatigue. Hamaheat outperforms.
Test methods: 302ºF (150ºC) after
168 hours operation.

Selecting the right heat-resistant belt:

1. The surface temperature of the belt varies with the type and size material being carried. With large lumps (e.g. sintered ores, coke) which allow air to circulate, the belt surface would be cooler than the lumps.

2. In the case of powdery or similar material, such as cements, alumina, carbon back, etc., there is almost no temperature differential between material and belt surface. Therefore, in selecting a belt, it is necessary to know not only the temperature of the material to be carried, but also to have an accurate idea of the surface temperature the belt will be operating at. Some examples of such temperatures are shown in the following table.
