19 06 2019 The different components of a belt conveyor system typically are electric drives pulleys idlers and a long belt. A simple conveyor system may look like below The basics of the Calculations of Conveyor Belt Design Parameters. Belt tension The belt of the conveyor always experience a tensile load due to the rotation of the electric drive

Understanding a basic conveyor belt calculation will ensure your conveyor design is accurate and is not putting too many demands on your system. Tight Side Tension. Total tension to move belt and load horizontally E 2 = E E 1. Slack Side Tension. Additional tension required to prevent slippage on drive pulley E 1 =E x K.

22 08 2010 The belt tension at steady state can be calculated as Tb = 1.37 f L g 2 mi 2 mm cos δ H g mm .eqn.1.1 Where Tb is in Newton. f = Coefficient of friction L = Conveyor length in meters. Conveyor length is approximately half of the total belt length. g = Acceleration due to gravity = 9.81 m/sec2 mi = Load due to the idlers in Kg/m.
