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 meal; these reactions also involve combustion processes. The grate cooler is located downstream of the clinker rotary kiln with the purpose of suitably cooling the clinker. …

even, and the clinker remains too hot at the outlet of the cooler. In the case of a thin layer, the air passes rapidly through it and the heat recovery is poor, resulting in reduced tem-

What Is Clinker Cooler? In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of a cement rotary kiln, a clinker cooler (also called cement cooler) …

(Steuch, 2014). In cement manufacturing, a grate clinker cooler system is employed, and the clinker burning system comprises of a clinker cooler, rotary kiln, and suspension pre-heater. A clinker cooler lowers the clinker's temperature and grinds and recovers energy from the hot clinker's sensible heat by heating the cooled air.

Energy, 2012. Grate coolers are widely used in cement industries to recover heat from hot clinker, coming out from the rotary kiln. This study focuses on improving the energy, exergy and recovery efficiencies of a grate cooling system through the optimization of its operational parameters such as masses of cooling air and clinker, cooling air temperature, and grate speed.

the cooler is equipped with a rectangular roof provided with two exits, the clinker bed is uniform and rectangular in both hot and cold zone, the clinker consists of homogeneous spherical particles with an average diameter of 15 mm and of a bulk density of 1500 kg/m3, the porosity of the clinker bed is supposed equal to 0.4,

improved the design of rotary kilns; they added a cooler to facilitate grinding and improved the quality of the clinker [5]. These improvements thus increased kiln production volumes while yielding a more homogeneous output. Satellite or planetary coolers came into existence in the 1920's, consisting of a set of tubes (usually 7 to

clones (P), Calciner (Ca), Rotary Kiln (K), and Cooler (Co) The production of clinker comprises several process equip-ment: a pre-heating tower (with a set of cyclones), a calciner, a rotary kiln, and a cooler, see Fig. 1. As the formation of clinker takes place in the rotary kiln, this paper focuses on formulating a dynamical model for the ...

Secondary air is the hot air entering the rotary kiln via clinker cooler. Its flow is determined by the combustion of the burning zone fuel. While cooling the clinker, it reaches temperatures of 600 to over 1000°C, depending on type and condition of the cooler.
