Abstract： Using dry grinding process, the effect of five kinds of selected grinding aids such as glycerol, sodium silicate， triisopropanolamine, triethanolamine， and sodium ligninsulfonate on grinding efficiency of foam glass batch was researched. By changing the dosages of grinding aids， grinding granularity of the foam glass batch was used to assess the effect of the grinding aids to grinding efficiency of foam glass batch. The results show that the grinding efficiency improves with the increase of aid dosage. But there is an extremum for the grinding efficiency, which is associated with kinds and dosages of the grinding aids. Triethanolamine is the best aid of the foam glass batch and the best dosage (mass fraction) is 0.04% . Average particle size of the foam glass batch is 13 μm, which decreases by 43% compared with the blank.
