CEMENT RAW MATERIALS - International Cement Review

2013-6-9  Over recent decades there has been a move away from the wet process to the more energy efficient dry process. In Europe, for example, about 78% of cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry/semi-wet kilns, and only about 6% of European production now comes from wet process kilns.
