Abstract A dimensionless parameter, NRS, based on the probable number of passes through the shear zone for an ingredient to be dispersed, was developed for scale-up of mixing of short fiber composite in an internal mixer. A single curve was obtained for the dispersion-NRS relationship of three widely different compounds in five internal mixers of various sizes. The parameter is an improvement over previously reported scale-up parameters, because the temperature profile does not have to be matched for different size mixers. The dimensionless dispersion number concept can be extended to dispersion of other ingredients, as long as the shear stress generated at the mixing temperature is higher than the interaggregate cohesive force of the particles. Based on this parameter, NRS, the dispersion of short fibers can be predicted from one size of internal mixer to another size mixer. It is also possible to predict the mixing time required for a given dispersion rating.
