Conveyor belts with a low coefficient of friction

The fabric used in Nitta's curved conveyor belts reduces the coefficient of friction to 0.14 (coefficient of friction µ of backside on aluminum). This makes these types of conveyor belts particularly suitable for other applications. Not only will it be a solution for friction critical applications but also for applications where energy (drive) costs need to be reduced.

2.3.1 Coefficient of Friction

In this formula, a coefficient of friction is multiplied by every term in the equation. Therefore, if the coefficient of friction is high, the tension increases and larger chain is required. Also, the necessary motor power, which is calculated as tension × speed × coefficient, increases.

Static and kinetic friction – what exactly is the ...

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. In the worst cases, this can stop the conveyor belt completely.
