The old specification of the general conveyor belt is represented by the width (mm), the skeleton layer, the upper and lower covering glue thickness (mm) and the length (m) 5 digits. Such as: 500*5*3*2.5*100 said width of 500mm, 5 layer of adhesive tape, covering the thickness of the glue to 3mm, covering the thickness of the glue is 2.5mm, the length of the conveyor belt 100m. General production of commonly used 500mm*5P (3+2.5) *100 said. 

The new specification for the general conveyor belt is the longitudinal full thickness tensile strength (kN/mm), represents the general purpose of the letter G, ribbon width (mm), the covering layer performance level code (L for light, h for heavy, m for the general type), upper and lower covering the thickness of the glue (mm). such as a ring belt, also includes the belt inside circumference (m). In addition, it is necessary to have the content of the core material and layers. such as: Specification for 500GB800L3/1.5-30 (NN3) conveyor belts, representing longitudinal full thickness tensile strength 500kN/mm, general-purpose, belt width 800mm, covering layer performance level for light, upper and lower covering the thickness of the rubber is 3mm and 1.5mm respectively. The belt is circular, inside the perimeter is 30m, with the core material for nylon, has 3 layer fabric.
