368 A . A tmaca and R. Yumruta ú 1 Introduction Clinker, which is the semiproduct of cement, is an important construction material, which is produced by rotary kilns in cement industry.
The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
— The main objectives of the controllers are to control the rotary kiln and grate cooler critical process variables while minimizing the fuel/coal specific consumption of …
Rotary coolers were installed on the vast majority of kilns in the first quarter of the twentieth century. They were installed either beneath the firing floor, as in the original Hurry & Seaman designs installed by Fellner & Ziegler, or beneath the kiln.The latter design had the advantage that floor space required for the kiln system could be reduced, but meant that …
Improved hard process, among many, is a process based on rotary kiln that yields phosphoric acid with technical grade through producing agglomerate grains from phosphate, cock, and silica soil.
— The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw ...
— Barring the continuance of some old wet-process or semi dry process kilns in different countries, the new and modern plants almost exclusively operate dry-process 5 …
— In this paper, thermal energy analysis of three zones of a lime production process, which are preheater, rotary kiln and cooler, is performed. In order to perform a proper quantitative estimation, the system was modeled using energy balance equations including coupled heat transfer and chemical reaction mechanisms.
