In recent years typical kiln size has come to be around 3000 tonnes clinker/day. The clinker burning takes place in a rotary kiln which can be part of a wet or dry long kiln system, a semiwet or semidry grate preheater (Lepol) kiln system, a dry suspension preheater kiln system or a preheater/precalciner kiln .
Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main ...

Burning in a kiln – formation of cement clinker. Burning in a kiln – formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw ...
The processes of milling, blending, calcining and grinding the clinker are described as dry, semidry/semiwet or wet depending on how the raw material is handled before being fed to the kiln. Moisture content of the raw materials (ranging from 3% for hard limestone to
"Firing" in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its "asreceived" state. With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
