MAXX SURYA

Heat Resistant Conveyor Belt

Product Feature

MAXX SURYA belts are suitable for carrying high-temperature material, such as sinter, hot ash, clinker, foundry sand etc., MAXX SURYA has a wide range of Heat Resistant conveyor belts which we recommend depending not only on the thermal load on the belt but also based on the following factors:

  • Nature and composition of the material
  • Average and peak temperature of the material to be conveyed
  • Length of conveyor
  • The rate of cooling of a material
  • Belt speed
  • The surface temperature of the material at the discharge end
  • Shape, size, and coarseness of the material
  • The thickness of top cover

Several manufacturing processes involve heat generation or conveyance of hot material. While belt selection may be made on the basis of certain design criteria by the end users, it is often the case that due to process variables, the actual ambient conditions that belts are exposed to are much more than originally estimated.

Due to the severity of the operating environment and the intrinsic limitations in the material properties, belts tend to fail due to: Cover hardening | Ply delamination | Belt deformation | Joint failure.

High Abrasion Resistant grades are also available on request Note: For any specific cover grade requirement outside the chart, kindly contact Oriental’s Technical service division.

While conventional rubber covers had limited heat resistance, with the continuous evolution and development at Oriental, we have reached a stage where the rubber covers are capable of withstanding elevated temperatures of +200o C and resist cracking and hardening for a much longer period in operation.

This necessitated a relook at the thermal integrity of various reinforcement materials so that further improvements in this field would be undertaken.

KEVLARI

Carcass Types: It is a fact that most failures in high heat applications commence with rubber covers ageing prematurely and this is followed by fabric plies giving way. This is due to limitations in the thermal properties of conventional polyester and nylon fabrics which tend to soften and melt when the core of the belt reaches temperatures exceeding 150°C. At these temperatures there is a sharp drop in the strength of the belt and blow holes and joint failures are witnessed.

To address these challenges, the MAXX SURYA® belts are offered with the following carcass reinforcements MAXX STEELFLEXTM | MAXX ARMOURM | MAXX ROCK | EP/NN
