Predictive Model for Cement Clinker Quality Parameters
Managers of cement plants are gradually becoming aware of the need for soft sensors in product quality assessment. Cement clinker quality parameters are mostly measured by offline laboratory analysis or by the use of online analyzers. The measurement delay and cost, associated with these methods, are a concern in the cement industry. In this study, a regression-based model was developed to ...
Optimization Design of the Grate Cooler Based on the Power
Dec 18, 2019 As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization. Then, the grate cooler was simplified into a series-connected heat exchanger network by power flow method.

Cement Kilns Clinker Thermochemistry
In the example clinker, the total sensible heat transferred to the feed in rising from 25 to 1425 C is 2134 kJ/kg, while the sum of the reaction endotherms at the reaction temperatures is 1695 kJ/kg. Of course, in an efficient kiln system, most of the sensible heat is subsequently recuperated and re-cycled.
Simulation model for the calcination process of cement
Once the clinker esleav the kiln, a cooler is introduced ininject cold air to lower the temperature from 1.400 C to 100 C. The hot air generated in this device is returned to the kiln to support combustion, thereby improving the energy efficiency of the process. 2.4 Grinding of the clinker. Once the clinker is obtained, it is mixed

A method of manufacturing cement clinker includes a rotary cement kiln having a feed end, a mid-kiln feed location, and a burning end. The rotary kiln is tilted downwardly from the feed end to the burning end so that material introduced into the feed end travels downwardly to the burning end. Heat is directed at the burning end of the rotary kiln.
