Classification of Particle Size Density for Cement Production

The final step in cement production is the grinding of clinker with gypsum and supplementary materials (blast furnace slag, fly ash…). Clinker is an intermediate product, formed in a rotary kiln at 1450°C. The particle size distribution of the clinker depends on the conditions in the rotary kiln.

Cement Kilns: Exhaust gas handling

The rate of dust pick-up is controlled by the shape of the feed particle size distribution curve and the individual particle terminal velocity. The concentrations of bigger kilns in the 1930s gave the cement industry a bad reputation for dust emission, with drifts of dust in the streets of the main industrial areas.
