Environmental effects on grinding - ScienceDirect

1983-6-1  (2) The effect of addition of surfactants on hardness, microhardness, crushing strength and wet grinding of haematite has been investigated. (3) Surfactants such as sodium oxalate, acetone, sodium tripolyphosphate and potassium dihydrogen phosphate, which act as dispersants, have been found to decrease the hardness, crushing strength and increase the grinding efficiency of haematite.
