It is well known that the temperature of the gaseous emissions and the emission concentrations are higher when the rawmillwas off (in thedirectoperatingmode). For Oujdacementfactory, thedirectoperatingmodelasted about 25–30% of the total running time.

When themillis out ofoperationthekilnis run indirect mode. Thekilnis run indirect modetypically 10% of the time during a day. The flue gas is then bypassed theraw mill, the air leak in themillis eliminated, and the CO2 concentration at the stack is consequently higher (up til 35%), while the flue gas flow rate is lower than in the interconnected mode.

The operating principle of the ball millconsists of following steps. In a continuously operating ballmill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

The original rotarycementkilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated ...
