conveyor belt ruber  Characteristics:

Heat Resistant Conveyor BeltThe carcass of the heat resistant conveyor belt selects cotton canvas or EP canvas as skeleton material. This kind of conveyor belt adopt ethylene-propylene rubber or syrene butadiene rubber as coating with good heat resistance. Heat Resistant Conveyor Belt is the best choice.Suitable for conveying hot material like powder or clump materials at high temperature.Ideal for conveying sintered ores, cokes, soda ash, chemical fertilizer, slag and foundry.It can resist high temperature.The rubber compound used in the cover have been designed to avoid premature aging due to contact with any source of heat.It can be divided into four types according to working temperature range: HRT-1 <=100°C, HRT-2<=125°C, HRT-3<=150°C,HRT-2<=175°C

 

Models:Heat resistant conveyor belts fall into three modelsMode1: able to with stand the test temperature of less than 100°C, code S1 Mode2: able to with stand the test temperature of less than 125°C, code S2 Mode3: able to with stand the test temperature of less than 150°C, code S3 Mode4: able to with stand the test temperature of less than 175°C, code S4

 

The physical and mechanical properties of the heat resistant covering layer after tested should be in accordance with the following table:

 

Project		The type
		T1	T2	T3	T4
		Change the range
Hardness	Draw the intensity	+20	+20	+20	+20
	Maximum after wearing out	85
Draw the intensity	The minimum value Mpa after wearing out	12	10	5	5
	Performance rate of change /%	-25	-30	-40	-40
Break person who extend	Performance rate of change /%	-50	-50	-55	-55
	After aging rate of change /%	200	200	180	180

 

 

The heat resistance conveyor belt physical property of the cover rubber after heat test shall conform to the values specified in the table.
