· VDZ, IKN and HeidelbergCement (HC) have successfully managed to cool clinker under oxyfuel technology conditions. The innovative oxyfuel clinker cooler prototype has successfully been tested in a HC plant in Hannover. The overall aim of this experimental work was the testing of an oxyfuel clinker cooler in an industrial environment in order to assess its cooling performance (efficiency), as ...
cooling of the clinker. KuniiLevenspiel  proposed the representation of gassolid continuous crossflow heat exchange by a series of stages fully mixed crosscurrent contacting. Based on this configuration, the developed model allows the calculation of temperature profiles of the clinker, air and wall along the cooler which are inaccessible by
· For the cement clinker, a macroporous unconsolidated porous medium, seepage heat transfer theory can more accurately reveal its internal problems. Because of the macroporous characteristics of the cement clinker accumulation body, the changes in the physical properties of the surrounding air, such as viscosity, density, and so on must be taken into consideration in the cooling .
These coolers have two main advantages: they cool the clinker rapidly, which is desirable from a quality point of view (to avoid that alite, thermodynamically unstable below 1250 °C, revert to belite and free CaO on slow cooling), and, because they do not rotate, hot air can be ducted out of them for use in fuel drying, or for use as precalciner combustion air.
The cooling rate from 1¢90~ of the clinker without Na~O was varied in two ways: quenching in air and slow cooling at 20~/min in the furnace down to 1000~. Hereafter, we call these clinkers A] and A2 ...
This paper aims to present efficient efforts to optimize the proportionalintegraldifferential (PID) controller of clinker cooling in grate coolers, which have a fixed grate and at least two moving ones. The process model contains three transfer functions between the speed of the moving grate and the pressures of the static and moving grates.
Cooling l3OO'C I S+C2S+C3A +C# Figure 4. Approximate reaction sequence in clinkerization. BumczbiMy and Clinkerization 37 Clinker PhasesEffect of Cooling Rate It has been seen that the clinker phases, as well as the melt formed during sintering, get affected by the rate of cooling.

calcite in some clinker samples from the clinker cooler prototype. Infrared spectroscopy (IR) at 950 °C for CO2 and H2O analysis of the same samples showed the presence of up to mass% CO2, confirming the QXRD results. However, not all samples cooled with a CO2 rich cooling medium showed significant amounts of calcite or CO2.
Clinker cooling is one of the important processes in cement production. Improving the cooling effect is not only beneficial to improve the quality and grindability of clinker, reduce the power consumption of the cement mill, but also can reduce the clinker temperature, recover the waste heat, and create favorable conditions for subsequent cement handling, storage, or transportation.

The cooling zone in the kiln is actually quite short but it is in this zone that nodulisation of the melt occurs. The red hot clinker is then discharged into the cooler, where it is quenched cooled to around 100 degrees centigrade. The heat dissipated by the clinker .
The rate of cooling affect the degree of crystallization and the amount of amorphous material present in the cooled clinker. The properties of this amorphous material, known as glass, differ considerably from those of crystalline compounds of a nominally similar chemical composition. The percentage of the main composition of cement can be ...
Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker. Besides, the rapid cooling of the clinker in this process is convenient for cement storage and transportation.
· In this instrumentation project we are dealing with the clinker cooling system in a cement manufacturing industry. Automation is the use of control systems (such as numerical control, programmable logic control and other industrial control systems), in concert with other appliions of information technology (such as computeraided technologies CAD, CAM, CAX), to control industrial .
subsequent calculation was based on the principle of input (clinker, cooling air, fuel, water injection) and output (clinker temperature, secondary and tertiary Air, excess air and cooler radiation) of clinker from the grate cooler. Cooler Input The cooler clinker input is considered as 1 kg which is taken as the basis for the mass.
Clinker comes out of the kiln as grey balls, about the size of marbles. Clinker is discharged redhot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency.
· Clinker formationconcepts 1. Introduction: Why study clinker burning? "To understand the influence of changes in kiln operation conditions" Normal kiln operation Influence of chemistry, fineness, mineralogy changes Influence of new mix components (pozzolan, AFR, sand, etc.) Abnormal kiln operation know causes of badly burnt clinker understand why rings and deposits form be able to .
· Clinker Grate Cooler for Cement Plant. Diffusion, cooling the hot clinker. Cooling air after cooling process becomes hot air, and the hightemperature hot air is used as combustion air into the kiln and decomposition furnace (predecomposition kiln system), and some hot air can also be used for drying, and extra hot air will be discharged into the atmosphere after dustremoving.
