Özet

The effects of PSS (sodium polystyrene sulphonate) and NSF (naphtalene sulfonate formaldehyde condensate) chemicals used to control the pulp rheology, on the grindability of coals were studied. Zonguldak region bituminous coal and Istanbul region brown coal samples, which have different structures, were used in the test work. Wet grinding tests with two coal samples were performed with and without PSS and NSF under constant grinding conditions; the solid ratios ranged from 50 to 60% with 0-60 min grinding periods.
