Apr 20, 2020· This formula differs from the friction factor based formulations in the inter national standards like DIN-22101 and ISO-5048 in one important aspect: the CEMA classic method provides designers with charts of friction factor vs belt tension, belt load, temperature, and idler pitch. The other standards simply state that belt friction should be set based on the experience of the designer, but

Belt conveyor drive The horsepower, hp, required at the drive of a belt conveyor, is derived from the pounds of the while operating at design capacity. conveyor belt, belt conveyor calculation
(Te in lbs) x (V in fpm)/((33,000 ft-lbs/min)/HP) = HP; After calculating Te, it is important to calculate T2 slip (slack side tension required to resist slippage of the belt on the pulley.) The historical method that CEMA provides to calculate T2 slip is as follows: T2 slip = Te x Cw, where Cw is the CEMA wrap factor for a rubber surfaced belt.

The historical method that CEMA provides to calculate T2 slip is as follows: T2 slip = Te x Cw,where Cw is the CEMA wrap factor for a rubber surfaced belt. The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420° of wrap angle, or as large as 1.2 for a single drive system
