Introduction :In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.

The carbonate rapidly resolved and occur a series of solid-phase reaction in rotary kiln to bring the mineral into being.As the material temperature close, the liquid will become minerals dissolved in the liquid phase reaction and generates a large number (clinker). After the clinker burning, the temperature began to decrease.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400 C-1500 C in the rotary kiln.

The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it
The exact dosage must be determined by optimization of mill productivity and cement properties through plant trials. PDX-105 products can be sprayed onto the clinker on the conveyor belt to the ball mill, or injected directly into either ball mill compartments.
As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease. As a leading cement plant manufacturer, AGICO Cement supplies cement equipment for clinker plant, such as cement rotary kiln, preheater in cement plant

Clinkerization - Cement Plant Optimization
Jan 07, 2015 Answer-8: The liquid has a critical role in clinker nodulization and clinker mineral development and properties. Solid-solid reaction is very slow process while solid-liquid reaction kinetics is much faster, so without liquid phase (figure-10) the diffusion of Ca ions towards C2S would be extremely slow, and the conversion of C2S and free lime

Jul 18, 2021 With increased liquid phase an acceptable range of f-CaO can be achieved at lower temp which helps to lower energy consumption and increase rate of heat exchange, therefore increase output. Belite + f-CaO =Alite. k = Alite/(Belite + f-CaO) where k is the degree to which this conversion is completed in clinker.

Effect of clinker composition on mill performance Energy Consumption (kWh/t) C 3 S / Al 2 O 3 / Fe 2 O 3 Energy Consumption (kWh/t) C 2 S / Liquid Phase / SR Favourable Adverse “Rule-of-thumb”: o Every 1% increase in C 3 S, the grindability decreases by ~1.5%; o Every 1% increase in C 2 S, the grindability increases by ~2.5%.
Clinker and gypsum are ground in a Fema tubular ball mill, 3.8 x 13.75m in a closed circuit consisting of a results of industrial tria third generation Humboldt separator, 3,5 m with four cyclones. The gases exiting from the mill are filtered by means of a bag filter. Grinding additive is added to the first chamber of the ball mill.
At most manufacturing plants the ball mill is used to grind the clinker and, since the production rate is directly related to the amount of electrical energy supplied, the power of the electric motor used to turn the mill is a first-order measure of the output achieved. Mills vary in their power input from as little as 200 kW up to 10000 kW.
Portland Cement Clinker - an overview | ScienceDirect Topics
The composition and content of liquid phase have the significant influence on the C 3 S formation in the pro- duction of clinker. The liquid phase are mainly composed of CaO, Al 2 O 3 and Fe 2 O 3 in burning process. The vis-cosity of liquid phase varies with the ionic state in the liquid composition. CaO is always dissociated into Ca2+ ions
