2020-10-1 Accordingly, this study seeks to investigate the use of new GAs in dry grinding regarding energy reduction as well as their effects on product surface properties to improve dry grinding. The goal is to perform a comparative interpretation of the application and effects of GAs on dry grinding of magnetite ore (as one the most important ores within Sweden) and the resulting product surface properties.

Study on Grinding Effect of the Different Grinding

To improve the grinding of cassiteritepolymetallic sulfide ores, this paper studied the effect of six kinds of grinding aids. We found that these six kinds of grinding aids can change the grinding effect, but only PAM can make the eligible size fraction increase and decrease the lack-grinding size fraction and the overgrinding size fraction, and reaches the effect of the original study
