jamaica friction of coal on conveyor

  • 231 Coefficient of Friction

    The tension ( T) in a horizontal conveyor, like that in Figure 222, is basically calculated by this formula: T = M1 × g × f1 × 11 + M1 × g × f2 + M2 × g × f3 Where: T = total chain tension M1 = weight of the chain, etc M2 = weight of conveyed objects f1 = coefficient of friction when chain, etc, are returning
