Usage
It is suitable for conveying high temperature solid materials like sintering ore, coke, cement clinker, etc. which is used in metallurgical, cement, chemical industry and so on.
Characteristics
Developed new structure carcass materials will reduce the strength loss of heat aging during running, and thus will extend the working life.
The cover uses superior ethylene-propylene rubber or halogenate rubber which will enhance the high temperature resistant property of the rubber and reduce the loss of heat aging.
