Composition of Cement Clinker

18/09/2018 · Tricalcium Silie: It is supposed to be the best cementing material and is well burnt is about 2550% (normally about 40 per cent) of cement. It renders the clinker easier to grind, increases resistance to freezing and thawing, hydrates rapidly generating high heat and develops an early hardness and strength.

Cement clinker

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 ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilie materials such as clay during the cement kiln stage.

Portland cement clinker

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.

It is the stage in which most of the operating costs in cement manufacturing appear and is also where most opportunities for process improvement exist. The main challenges at this stage in the clinker production are preventing blockages in the preheater, measuring the process accurately and maximizing production in this hot and rough environment.

Cement Manufacturing Process: What is Cement made of.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

The clinker manufacturing process

The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in preheater cyclones fitted with a precalciner fired with petroleum, natural gas or coal.
