    Fig. 2 shows a check chart list of the sources of dust in the cement-making process and the type of equipment generally used for cleaning the gases. Fig. 3 shows particle size distribution for dust and fume in dryer and kiln gases. It will be noted that for high recovery efficiencies, Cottrell Electrical Precipitators or filters are indicated..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.
