Heat Resistant Conveyor Belt

Comply with CEMA/RM, AS, GB standards for rubber conveyor belt.

Application

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

Category: Product ID: 2291

Description

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.

Product Varieties

  • 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℃.
  • 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.
Note
  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.
