Heat Resistant Conveyor Belt is mainly used for transporting high temperature materials, such as sintering ore, hot coke, cement clinker, hot casting, etc. According to the manifestation of that the belt is damaged till it's out-of-function, and according to its heat resistant grade, we use EPDM or SBR as cover rubber and use high-strength EP or cotton canvas as tension element. Heat resistant woven glass fabric can be placed between cover rubber and belt canvas, so as to improve its working life. We can manufacture endless belt as per clients' requirements.
