This method is called a semi-dry process, which belongs to the cement dry process production. Advantages: as the dry process is to directly feed raw material powder into the rotary kiln for calcination, and the moisture content of raw materials is about 1% – 2%, it saves the heat consumption needed for the moisture evaporation. Therefore, this method has the advantages of energy-saving, high …
