11.6 Portland Cement Manufacturing

1971-8-17 · Five different processes are used in the portland cement industry to accomplish thepyroprocessing step: the wet process, the dry process (long dry process), the semidry process, the dryprocess with a preheater, and the dry process with a preheater/precalciner. Each of these processesaccomplishes the physical/chemical steps defined above. However, the processes vary with respect toequipment design, method of operation, and fuel consumption.
