Abstract

The effect of PSS (Sodium Polystyrene Sulphonate) and NSF (Naphthalene Sulphonate Formaldehyde Condensate) chemicals used to control the pulp rheology on the grindability of coals was studied. Zonguldak region bituminous coal and Istanbul region brown coal samples that high and low rank were used. Wet grinding tests with two coal samples were per-formed with or without PSS and NSF under constant grinding conditions: solid ratios ranged from 50% to 60% with 0-60 min grinding periods.
