Clinker is the main constituent of portland cement. Clinker consists of calcium oxide and other mineral oxides (iron, aluminum, and silicon) and has cementious activity when reacted with water. Clinker is produced by pyroprocessing in large kilns.
Pyroprocessing and Finish Milling In pyroprocessing the raw mix is heated upto C to produce Portland cement clinkers Clinkers are created from the chemical reactions between the raw materials The pyroprocessing takes place in a kiln A kiln is the heart of any cement plant. Pyroprocessing in cement plant.
Jan 01, 2016· Portland cement is a complex product made from very simple and abundant materials: limestone and clay (or shale). Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition; this will result in the production of clinker through the complex pyroprocessing presented in Figure 3.1.
the Portland Cement Association (PCA) has expanded its data collection efforts to obtain ... processing (i.e., pyroprocessing) of substantial quantities of these raw materials in huge kilns at very high and sustained temperatures to produce an intermediate product called clinker. Cement
produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs. The rotary kiln is approximately 20 to 25 feet (ft) in diameter and from 150 ft to well over 300 ft long; the kiln is set at a slight incline and rotates one to three times per minute. The kiln is most
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement. The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.

This is called pyroprocessing, it causes a physical or chemical change to the materials and it is the most energy intensive part of the process (Portland Cement Manufacturing Section 11.6, 1). The mix is then cooled and mixed with the gypsum and limestone (How Cement is Made)(Reference Figure 1).
