The lazy plumes of static kilns carried little dust, and such dust nuisance as existed on early plants was from the manual packing of finished cement. But rotary kiln exhaust gases were normally heavily laden with dust, and the first generation kilns made no attempt at all to prevent it entering the atmosphere.
A typical degree of calcination of limestone on entering the rotary kiln from a precalciner would be about 90 per cent, so nearly all the heat requirement for calcination is in that early stage of clinker-making and not in the kiln.
