Introduction of Cement Rotary Kiln
Cement rotary kiln is the main equipment for dry and wet production of cement clinker.Rotary kilns are widely used in metallurgy, chemical industry, construction, refractories, and environmental protection industries. The rotary kiln firing system is equipment with technological innovation.This system adopts the domestic advanced technology,such as the most advanced hydraulic block wheel device, a high measurement accuracy of measurement piston pump, high-precision control valve and contact-type graphite block sealing device.
Features of Cement Rotary Kiln
The structure of kiln is simple, operate conveniently and reliably in life, less wearing parts, high rate of operation, it is the equipment to calcine high-grade cement in cement plant. Meanwhile, it is also widely used in metallurgical, chemical, construction and other industries. The rotary kiln produced by my company is with strong structure, operation smooth, high-quality products etc and can provide users with advanced high-performance vertical pre-heater, 5 degree cyclone pre-heater.
Cement Rotary Kiln Processes Wet and Dry Cement Rotary Kiln
With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal".
- In the Wet Process, the kiln system is fed with liquid slurry, the water then being evaporated in the kiln.
- In the Semi-Wet Process, raw material is prepared as a slurry, but a substantial proportion (50-80%) of the water is mechanically removed, usually by filtration, and the resulting "filter cake" is fed to the kiln system.
- In the Dry Process, the kiln system is fed with dry raw meal powder.
- In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system.
