jointless endless round rubber conveyor belt

jointless endless round rubber conveyor belt   Endless conveyor belt is conveyor belt that has been made into in to endless without joint in the process of production. Its feature is that there is no joint in belt carcass, and the belt sell not be shortened in service life due to early failure in the joints of the belt. The belt is flat in surface and even in tension, thus it runs smoothly and its elongation in working is low.  

We can manufacture endless belts with seams and seamless.   Features of jointless endless round rubber conveyor belt:
1.no joint,smooth belt surface 2.even tension 3.belt can run smoothly 4.small elongation   5.low power consumption,high working efficiency   Specifications of jointless endless round rubber conveyor belt :    1.belt core material:cotton canvas,nylon canvas,EP canvas.
2.width:300-1600mm
3.thickness of covering rubber:working side:1.5-8mm,non-working side:0-4.5mm.
4.number of fabric layer:2-8
5.Types:according to the property,it can be divided into ordinary type,heat resistant type(≤120°C),cold resistant(above -40°C),acid and alkali resistant,high temperature resistant(below 150°C),etc.      
Applications of jointless endless round rubber conveyor belt:   • mining,coal mine • chemical industry • quarry & stone factory • cement & concrete plants • cogeneration powder plant • metallurgical & foundry industry • port & wharf loading and unloading • steel mill & metal processing industry • building/architectural material industry • hydropower station construction site
