Saving Energy in a Cement Plant – Cement Products
The majority are raw meal and cement mills, designed as either vertical or ball mills. Cement production runs continuously with very limited reserve capacities and little redundant plant or equipment. The greater part of the equipment therefore has to run around-the-clock or – if there are specific restrictions – throughout the day.
