  • Mechanochemical aspects in wet stirred media milling

    Liquid phase analysis during processing reveals high reactivity. Abstract. Wet comminution in stirred media mills is a frequently applied fully scalable top-down method towards the production of micron- and submicron particles. Despite the vast field of mechanochemistry which encompasses an increase in reactivity due to the effect of mechanical

  • Estimation of product relating energy of wet operated

    This energy transfer is dependent on the mill geometry and the adopted fluid phase. Wet stirred media mills are always operated with a fluid phase, thus the liquid (here water) was used to measure the minimum power consumption of the mill, to reflect its influence on the friction behavior between grinding media and mill.
