Chevron conveyor belt is composed of belt carcass and pattern. Pattern shape and height(depth) may be different because of different conveyes material and gradient of conveyors.
Application
It can convey powdered,granulates and small lump materials at the gradient of no more than 40;it can also convey packaged materials.

Mold drawing
The belt core of this product is made of polyester canvas with high modulus, low shrinkage, and extremely high breaking strength, and the covering rubber is made of EPDM or chlorinated butyl rubber with good high-temperature resistance, which is refined by processes including compound molding with high-temperature resistant materials and vulcanization.
After special stain setting treatment, the belt core of this product provides high adhesive strength. Under normal conditions of use below 180 ℃, the product offers small elongation and deformation, and excellent wear performance.
It withstands the high temperature of 250ºC for a short period of time.
It is suitable for use in cement, coking, metallurgy, steel, and other industries.
