    Cyclone preheater, also known as suspension preheater, is the main cement equipment commonly used in the new dry process cement production line. It is the main gas-solid reaction unit of the cement raw meal pre-decomposition system, which makes full use of the high-temperature exhaust gas discharged from the kiln tail and the high-temperature flue gas generated by the combustion at the

  • Preheater Cyclone In Cement Plant Thermal Efficiency

    The 5-stage suspension preheater cyclone is the device inside which the cement raw meal performs heat exchange with hot gas from the rotary kiln and is preheated. It is one of the key equipment in the cement clinker production line, and its efficiency directly affects the production efficiency of the whole plant and product clinker quality.. The index we usually use to measure the efficiency ...

    transfer heat from gases to the material. In the cyclone of pre heater there are two parts. The upper part called riser duct raw meal is meant for heat transfer, whereas the cone and cylindrical part acts as a separator. Material falls down and is transferred to another cyclone whereas gases are sucked by means of pre heater fan.

    Aug 17, 1971 Five different processes are used in the portland cement industry to accomplish the pyroprocessing step the wet process, the dry process long dry process, the semidry process, the dry process with a preheater, and the dry process with a preheaterprecalciner. Each of these processes accomplishes the physicalchemical steps defined above.

    In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At A, the raw meal largely decarbonates at B, the temperature is 1000 C - 1200 C and intermediate compounds are forming and at C, the burning zone, clinker nodules and the final clinker minerals form.

    preheater used to be 500 to 550 mmwg. Any increase in number of stages resulted in additional pressure drop which unfavorably offset gain in fuel efficiency. Therefore cement industry continued for quite some time with 4 stage preheaters till cyclones of low pressure design were developed. Attention
