The exponent values for both mills were found to be −2.40 for stirred annular mill and −3.95 for pin-counter pin mill, respectively. This illustrates that both mills behave differently with regard to the bead filling rate. This could be explained by the contribution of the bead mill to increase the overall viscosity.
