Belt Conveyors for Bulk Materials - Fifth Edition - Chapter 6
89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t , K x , and K y , are used in calculations of three of the components of the effective belt tension, TAbrasion standards and test methods - Dunlop Conveyor Belting,There are two internationally recognised sets of standards for abrasion, EN ISO 14890 (H, D, and L) and DIN 22102 (Y, W, and X). The longer-established DIN standards are most commonly used in Europe. Generally speaking, DIN Y (ISO 14890 L) relates to ‘normal’ service conditions and DIN W (ISO 14890 D) for particularly high levels of,#23 Abrasion Resistance of Conveyor Belts,An example is shown below where a belt manufacturer measured the wear of three different covers with different lab abrasion numbers. As can be seen, the wear trend is similar, where the lower the lab abrasion number, the less the actual wear in service. With regard to standards, there are no USA standards on conveyor belts using this abrasion test.
