    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

    After the raw materials are calcined to clinker, the temperature begins to decrease. Finally, the high-temperature clinker discharged from the rotary kiln is cooled by the cement clinker cooler to the temperature that the downstream transport, storage, and cement mill can bear. Meanwhile, the heat of the high-temperature clinker is recovered by the cooler to improve the thermal efficiency and
