Cover thickness

Cover thickness:

The thickness of the top (carrier side) and bottom (running side) covers is given in millimeters (mm). The thickness of the top cover depends mainly on the type of transported material and the conveyor parameters, such as the load method, the height from which the material falls on the belt, the angle of inclination, etc. The rubber bottom cover protects the fabric dividers from the action of the conveyor rollers. The minimum tolerance of the cover thickness cannot be more than 0.2 mm for a thickness of 4 mm and not more than 5% for a thickness of more than 4 mm. There are no standards for maximum cover thickness tolerance.

Cover quality:

The quality and structure of the surface (smooth or profiled) should be selected according to the type of transported material and working conditions. Rubber quality and parameters related to wear resistance, etc. must comply with DIN or ISO standards .

DIN 22.102-1/04-91

Cover class	W	X	Y	Z
Min. tensile strenght (N/mm)	18	25	20	15
Max. stretch at break	400	450	400	350
Abrasive Consumption (mm³)	90	120	150	250

ISO 15.236 (2006)

Cover class	H	D	L
Min. tensile strenght (N/mm)	24	18	15
Max. stretch at break	450	400	350
Abrasive Consumption (mm³)	120	100	250

The above values do not apply to special conveyor belts with characteristics corresponding to the markings T, G, A and C.

In addition, DIN 22.102-1/04-91 also covers belts with special characteristics for which mechanical values have not been established.
