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.

01/10/2020 · This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound called clinker.

Unstable coating easily leads to problems with the refractory material and causes loss of energy and disturbs stable kiln operation. Various measures can be taken to assist formation and maintenance of stable coating in the kiln burning zone. Preventing fluctuation of components in raw meal. Preventing the fluctuation of fuel combustion status.

24/10/2012 · Avoiding the formation of rings in rotary kilns is an issue of primary concern to the cement production industry. We developed a numerical combustion model that revealed that in our case study rings are typically formed in zones of maximal radiative heat transfer. This local overheating causes an overproduction of the liquid phase of the granular material, which tends to stick to the oven's ...
