cement preheater working

Thepreheateris a component installed upstream of the calciner and the rotary kiln of a clinker/cementplant. By means of the counterflow principle, the injected raw meal is heated in stages by the upward flow of hot gas, whereby the meal is calcined (deacidified) by up to about 95 %.

Cyclone Preheater in Cement Plant Suspension Cement
Cyclone Preheater in Cement Plant Suspension Cement

In the new dry process ofcementmanufacturing, the raw meal must bepreheatedin thepreheaterbefore entering the rotary kiln for calcining. The quality of thepreheaterin acementplant directly affects the stability of calcining temperature andcementclinker quality in the kiln. By using the computer numerical simulation technology to simulate the gas-solid two-phase flow field of thecementplantpreheatingsystem, we can design the optimal cyclonepreheater…
