Mechanisms Grinding Additives

About this site

effect of chemical additives on grinding cannot be attributed to a single mechanism, but that the cumulative effect on different pulp properties has to be taken into con-sideration. Examination of the effect of all properties has led to a better understanding of the mechanisms responsible for the ob-served grinding aid effects in the present study.
