Heat Resistant Conveyor Belt
Our heat resistant conveyor belt adopts SBR or EPDM as covering layer, special high temperature resistant canvas as carcass materials, not only solving the fabric shrinkage and deformation problems under the environment of high temperature, but also avoiding crucial problem as high degree of saturation of ethylene propylene rubber, poor adhesion. It is lighter, of long lifespan (about 2-4 times) and good performance of heat resistance.
2. 产品执行GB/T2002-2005 及GBAT7984-2001 标准，参考国际标准草案ISO/FDIS14890-1999。
1.Specification is similar to common conveyor belt.
2.GB/T2002-2005 and GB/T7984-2001 Standard are applicable with the international Standard draft ISO/FDIS14890-1999 as reference.
3.Heat resistant conveyor belt is divided into three types as follows:
HR120: cover consists mainly of SBR. The belt surface temperature of HR120 belt should be lower than 120℃,the maximum material temperature for short period can reach 170℃. This grade of Heat resistant conveyor belt is mostly common used traditional heat resistant conveyor belt, widely used in Cement, coking, metallurgy, chemical,iron and steel industry, etc
HR150: cover consists mainly of SBR. The belt surface temperature of HR150 should be lower than 150°C,and the maximum material temperature for short period can reach 200℃. Comparing to common conveyor belt, the product is higher temperature resistant, cracking resistant, ageing resistant and of long lifespan. It apply to transport high temperature material as sintered ore, clinker, coke, dry lime, dry clay, etc.
HR180: cover consists mainly of EPDM. The belt surface temperature belt of HR150 should be not higher than 180℃, and the maximum material temperature for short period can reach 250℃,Comparing to common conveyor belt, this kind of belt is more cauterant resistant. It forms a dense carbonized layers on belt cover under high temperature to play an effect of heat insulation and cauterant resistance , which can also extend the belt life . It apply to transport high temperature material as special transport situation as sintering ore and cement field , etc.
The selection of heat resistant conveyor belt
Select different type of heat resistant belt according to the temperature, surface figure, viscosity condition and other concerned data of conveyed materials. For instance, when conveyed material have a temperature of 150℃,such as the coke or sintered ore etc, and have a relatively small contact area with the belt's surface temperature remains at 60-80℃. In contrast, when powdered material like cement is being conveyed, there is almost no temperature difference between material and belt surface. More information please refer to the following table.
