how to calculate elevator belt speed

18-07-2020 0183 32 Mar 22 2017 1rpm would move the belt at 1878mm/min which is too much so we expect the required rpm to be 1rpm The required velocity at the pitch diameter is 760mm/min so the required rpm of the conveyor sprocket is = 760/1878 = 0405 rpm The large driven sprocket is mounted on the same shaft as conveyor sprocket so it must also turn at 0405 rpm...
