conveyor belt tension formula metric mining industry

and therefore an adjustment is made to calculate the effective tension. L C = L + 70 m (metric) L C = L + 230 ft (imperial) Therefore, the belt length correction is: C = L c L All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping.

Learn MoreTH = H x MW. TE = TC + TL + TH. Second, additional tension must be added to the effective Belt Tension (Te) to prevent slippage on the drive pulley. This is called Slack Side Tension (Ts), or commonly called T2. Ts = D x Te. D = Drive factor (See Table B in Engineering Handbook). Next, the total tension To = Te + Ts.
