Hot-material conveyor belts show resistance to warm environmental influences and/or materials such as cement, steel or glass. The surface of the conveyor belt consists of a special rubber compound which is characterized by high adhesive strength, low ductility and excellent thermal protective properties. Conveyor belts that are manufactured in accordance with DIN 22102 can transport materials with a temperature of up to 180 °C – and even up to 250 °C for short periods.
Rubber cover in this type of belt is available in three types, T1, T2 and T3. The low temperature T1 rubber cover allows temperature range on materials within 70° – 150° or 200°C, while the belt surface temperature ranges between 60° – 120°C. With its heat hardening type feature, this rubber cover is suitable for low or medium temperature materials which are abrasive like coke, sintered products etc.
T2 and T3 are allowing temperature range of materials within 100° – 200° or 250°C. T2 is heat softening type, possesses almost non crack cover and is suitable for hot powdery materials and high temperature materials with medium abrasive like sintered ore products, cement clinker etc.
T3 is excellent wear resistant cover under high temperature and is suitable for lumpy materials or high temperature materials which are very abrasive like coke, sintered ore products etc.
HR conveyor belts are primarily used in the following industries:
