The hot farine exiting from the abgas which is a rotten gas that appeared in clinker production in the rotary kiln system.ventilation at point 5 passes through the cooling tower to transfer excess heat into the cooling flow, as illustrated in fig.1.under the steady-state and steady-flow conditions, the mass, energy, entropy, and exergy balance equations can be defined as for the cooling tower.
Clinker rotary kiln is a professional equipment designed according to the characteristics of clinker.the calcination process of clinker includes crushing and pre-homogenization, raw material preparation, homogenization of raw meal, preheating decomposition and clinker burning.
Kiln speed should be such that volumetric loading is within the range 10-15 and heat transfer is maximized.pre-calciner kilns generally rotate at 3.5-4.5 rpm.under normal conditions, kiln should be run with as high rpm as possible.higher kiln rpm improves clinker mineralogy and grindability.
