MAHAJAN CONVEYORS — MCI SERIES

Heat Resistant Conveyor Belts

Engineered for Thermal Endurance & High-Temperature Industrial Applications

In heavy-duty material handling, conveying high-temperature materials requires specialized belting solutions to prevent premature rubber degradation, carcass hardening, cover cracking, and ply separation.

At Mahajan Conveyors, our MCI heat-resistant conveyor belts are specifically engineered to withstand extreme thermal exposure while maintaining structural integrity. By combining advanced synthetic rubber compounding (SBR / EPDM) with heavy-duty carcass reinforcements, our belts deliver exceptional service life in demanding high-temperature environments.

Critical Selection Parameters for Thermal Belts

Selecting the right heat-resistant belt requires analyzing thermal load along with operational conditions. Our technical team evaluates key parameters to recommend the optimal belt grade:

Material Temperature

Average and peak temperatures at loading and discharge points.

Material Properties

Lump size, coarseness, fines, and cooling behavior.

Conveyor Setup

Belt speed, overall conveyor length, and ambient cooling rate.

Structural Design

Top cover thickness, carcass ply rating, and heat dissipation rate.
