When building up the ore was prevented by simulating the low pulp-level mill, the small ball volume did good work. With 60 percent solids, pebbles the same size as balls did about the same type of work as balls when dolomite was ground, but they failed in selective grinding of chert. Pebbles gave about 35 percent of the capacity and 81 …
