Technical Requirements

Comply with CEMA/RMA、AS、GB standards for rubber conveyor belt.


  • Features

  • 1. Carcass can be made from Polyester EP, Cotton CC, and Polyester Cotton TC with high strength and low shrinkage features.
  • 2. Both top and bottom rubber covers are thick and heat/high temperature resistant.
  • Application

  • Suitable for conveying sintered ores, cokes, cement clinker in metallurgical and building industries.

Product Varieties

  • 1. Heat Resistant Type:
  • T1: Working temperature is no more than 100℃, short-term peak temperature at 125℃.
  • T2: Working temperature is no more than 125℃, short-term peak temperature at 150℃.
  • T3: Working temperature is no more than 150℃, short-term peak temperature at 175℃.
  • 2. High Temperature Resistant Type:
  • T4: Working temperature is no more than 175℃, short-term peak temperature at 230℃.

How to Order

  • 1. Choose the right type of heat resistant belt based on the properties of conveyed materials, such as temperature, shape, and viscosity.
  • 2. Surface working temperature of the belt has a huge impact on the belt service life and the adhesion strength between cover & ply and ply & ply. Therefore, investigate the surface working temperature and other relevant working conditions carefully before choosing the belt type.


  • 1. Prevent the belt from oil. Oil in the coolants and conveyed materials will significantly damage the belt.

  • 2. Should take auxiliary measures to cool the surface of the belt on the return route.

  • 3. Keep the materials distributing evenly on the belt. If the equipment unexpected stops during normal operation, take immediate measures to remove the materials on the belt.

  • 4. Suggest hot vulcanized belt splicing for heat resistant conveyor belt.
