Friction Factor (Goodyear)

Friction is the resistance to motion a moving component experience. The overall friction in the conveyor belt system is a composition of the movement of the belt over the pulley or idlers, rolling resistance of idlers and pulleys, and belt drag due to misalignment. The frictional force is obtained by using empirical coefficients such as the Goodyears in the table below.




Detail Friction Factor C Length Factor Lo (m)
Grade - B - Horizontal or inclined conveyor temporary structure or in a sub-standard condition. 0.03 40
Grade - B - underground or other conveyors likely to operate under adverse conditions up to 150m in length. 0.03 40
Grade A - declined conveyor - permanent strrucutur e, clean and in good condition. 0.012 145
Grade B - declined conveyor - temporary structure, or in sub-standard condition. 0.022 60
Grade A - Horizontal or inclined conveyor - permanent structure , clean and in good condition. 0.022 60
Grade A - Underground or other conveyors likely to operate under adverse conditions and over 150m in length. 0.022 60
