APPLICATION NOTE 43/2022

HERZOG investigated the effect of methanol on the grinding of clinker using a disc mill. Application of 400 µl methanol resulted in a greater fineness of the material with an increase of the grain size fraction smaller than 45 µm by 10 to 20 %. Simultaneously, we monitored the acceleration of the grinding vessel revealing a significant impact of methanol both on comminution and agglomeration of clinker particles. The study results highlight the ability of acceleration monitoring to track the influence of, e.g., liquid GA and predict their effect on the grinding efficiency of disc mills.
