This research aimed to investigate the potential of partial substitution of cement raw meal with grinding sludge as an alternative raw material in Portland cement clinker production. Cement raw mixtures with up to 3% raw mix replacement were put through a burning process in a hightemperature furnace.
In the cement industry pyroprocessing (processing the raw material into cement under a high temperature, e.g., ... The raw meal (dried slurry) is subjected to high temperatures in a rotary kiln, where the reaction of calcination takes place (its final products are lime and CO 2).
Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Cement - Sympatec. During the grinding process from raw material to raw meal as well as during fine grinding of burnt clinker with additional primary components or additives, monitoring and control of grinding grade is crucial for assurance of cement quality and production efficiency.

In many modern cement manufacturing plants, waste from other industrial processes is blended with the raw cement materials to change the properties of the cement. This practice can reduce the use of raw materials in cement production. Carbon Sequestration . Carbon Sequestration is the capture and permanent, safe storage of the greenhouse gas CO 2.
Cement: Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Learn more about cement in this article.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Meat and bone meal – slaughterhouse waste due to bovine spongiform encephalopathy contamination concerns;
However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the ...
Re: Raw meal to clinker ratio. The true raw meal to clinker factor is given by: 1/(1 – Loss on ignition of kiln feed). It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.
