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.
