Cement kiln - Wikipedia

In the 1970s the precalciner was pioneered in Japan, and has subsequently become the equipment of choice for new large installations worldwide. The precalciner is a development of the suspension preheater. The philosophy is this: the amount of fuel that can be burned in the kiln is directly related to the size of the kiln. If part of the fuel necessary to burn the rawmixis burned outside the kiln, the output of the system can be increased for a given kiln size. Users of suspension preheaters found that output could

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The cement kiln

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker

US20040157181A1 - Method for manufacturing cement clinker ...

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.

Modeling of Pulverized Coal Combustion in Cement Rotary Kiln

Process of Clinker Formation in a Cement Rotary Kiln. As a rule, the kiln feed precalcined in the preheater and calciner still contains a certain amount of CaCO3 that will be calcined to form CaO in the kiln. When kiln feed undergoes the high temperature zone in the rotary kiln, a series of chemical and mineralogical reactions occur.

Jul 07, 2018  If the output clinker is powdered or in liquid state, then it cannot be used in further processing and will be wasted. In the current scenario, the kiln output is visually observed and the Clinker quality is hourly measured in the Laboratory. In the kiln, raw materials undergo burning around a temperature range of 1200°C to 1400°C.

Clinker Production - an overview ScienceDirect Topics

The clinker cooler exhaust is at a temperature near 200°C and is typically used for preheating the kiln or other parts of the clinker production process. The ORC and Kalina cycles have also been considered for use to recover the waste heat from the clinker cooler. The sCO 2 cycle could also be considered for both waste heat streams.
