coefficient of friction for conveyor belts

Light conveyor belts ? Determination of the coefficient of ...

The coefficient of friction of light conveyor belts has to be seen from two different aspects relevant to the choice of the reference material. One aspect is the friction of the underside of the belt. In practice, this is not critical because it is low. Regardless of whether a table of steel or of wood is used, the coefficient of friction is within the range from 0,2 to 0,3 in most cases.

06.01.2020  The coefficient of kinetic friction is therefore indispensable for the calculation of conveyor belts running on slider beds. Oil or sticky stuff, or sometimes just water, between the conveyor belt and the slider bed may produce adhesion of the belt (sometimes called the suction effect), thus increasing the friction and consequently the energy consumption.
