Cema/DIN/ASTM/Sha Standard Industrial Large Angle Patterned Ribbed Chevron Conveyor Belt

Industrial large angle patterned ribbed chevron conveyor belt
Features:
Pattern conveyor belt is the one where inclination angle is formed between the working surface (the patterned cover rubber) and non-working surface (planar cover rubber) and the belt carcass.
Application:
It can convey powdered, granulated and small lump materials at the gradient of no more than 60°, it can also convey packaged materials in order to preventing downslide of materials.
Chevron pattern
Feature: there is "chevron" pattern higher than the belt body on the belt surface, the pattern can be open type or closed, each kind of pattern can further be divided into three kinds-high, medium and low. 
Application: suitable conveying of powdery, granular and small-lump material at inclination angle of ≤40° or conveying of bagged material. 
Strip pattern
Feature: there is strip pattern higher than belt body on the belt body in transverse direction, the pattern is divided into three kinds-high, medium and low, each pattern can further be divided into loose and dense etc. according the placing space. 
Application: suitable for horizontal conveying of packages at inclination angle of ≤30°. In case of trough, it can substitute chevron-shaped pattern. 
Grainy pattern
Feature: there is grainy pattern higher than the belt body or recessed in the belt body on the belt surface, the recesses can also be made into square hole, or prismatic and cloth grain lines. 
Application: raised grainy pattern is suitable for conveying of soft packages or material needing holding power (e.g. carton) or slipless conveying. 
Recessed grainy pattern is suitable for conveying granular material at inclination angle of ≤45°. 
Segmental pattern
Feature: there is half-sector (or 1/4 circle) pattern on the belt surface. When the rubber belt is troughed, the pattern is closed into a sector (or half-circle), it is of embossed pattern. 
Application: suitable for conveying powdery, granular and lumpy material at large inclination angle of ≤60°. Suitable for conveying materials at relatively large inclination angle. It is widely used in the fields of coal, mining, electric power, metallurgy, chemical engineering, light industry, grains, etc. for material conveying. 

Performance indexes(GB/T7984)
Performance of cover

Performance of rubber cover	Tensile strength	H	MPa	≥24
		D	MPa	≥18
		L	MPa	≥15
	Elongation at break	H	%	≥450
		D	%	≥400
		L	%	≥350
	Abrasion loss	H	mm3	≤120
		D	mm3	≤100
		L	mm3	≤200
Thickness of rubber cover	The thickness of common top and bottom rubber cover is 3.0+1.5mm, 4.5+1.5mm, 6.0+3.0mm, and 8.0+4.0mm, respectively. Since under normal service condition, the major loss of the rubber belt is abrasion, we suggest customers to increase the thickness of rubber cover appropriately at the time of placing order so as to improve the use value of the rubber belt.

Note: The elongation of reference force in longitudinal direction over the full thickness of the belt is not greater than 4%.
