ball milling grinding aids

Study on Grinding Effect of the Different Grinding Aids ...

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 ...
