    Cement Rotary Kiln - International Cement Review

    Pressure drop across a 4 stage 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

    Successful on every level 2 An optimal process Today’s modern plant preheats raw meal to calcination temperature in a multi-stage cyclone preheater. Most of the calcination process takes place in a separately fired, stationary calciner, while the remaining calcination and clinkerization process takes place in a rotary kiln

    Cyclone Immersion (Dip) Tube for Preheater Lower Stages. Dip tubes have significant influence on the separation efficiency of a cyclone. In modern suspension preheaters it is standard to use cyclones with a dip tube for improved separation. Especially the design of a lower stage dip tube requires know-how and expertise in order to achieve a low pressure drop of the cyclone by retaining the

    May 27, 2016 Cyclone stage numbering - This is a divisive subject. Uncomfortably for those of us who have always numbered from the top, it must be asserted that, with the proliferation of cyclone preheaters of other than 4 stages, numbering from the bottom allows more meaningful correla- tion from kiln to kiln. iv • Cement Plant Operations Handbook 6
