Measuring Coefficient of Friction
The coefficient of friction =
the force required to hold the bottle stationary on a moving conveyor
the weight of the package
The coefficient of friction (CoF or µ (Mu)) describes the ratio of the force of friction between two bodies. Controlling coefficient of friction values on packaging lines is crucial. A consistent and steady value within a set range is required to stabilise packages for maximum throughput and to reduce loading on conveyor motors.
As well as maintaining a consistent CoF, it is important to achieve different CoF values at different zones along the packaging line.
