— Portland cement, the most common type of cement, is made by mining, and then grinding raw materials that include limestone, clay, and bauxite to a fine powder, called raw meal, which is then heated in a rotating cement kiln.This cement production process produces clinker (rounded nodules between 1mm and 25mm across) as the chemical …
Where, G is another constant. The majority of the kiln feed is limestone, which does not have to be finer than 125 µm. If an argillaceous limestone (cement rock) is used, it may be possible to obtain good burnability at particle sizes considerably coarser than this (since the effective calcite grain size is smaller than the particle size).

Clinker, the residue formed by high-temperature burning of coal or similar materials, plays an important role in the composition of cement and contributes to the properties of cement in different ways. ... Pellenq R. J.-M., Impact of Chemical Impurities on the Crystalline Cement Clinker Phases Determined by Atomistic Simulations, Crystal and ...
— A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media. As the clinker particles are ground further, smaller media are more efficient at reducing the particle size even further. Grinding can be either 'open circuit' or 'closed circuit'.
For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single ...
The cooler is the last step in the clinker production process. Last, but not least. The cooler has a vital role in ensuring the final quality of the clinker and enhancing process efficiency by recuperating process heat to the kiln. Not to mention the job that gives it its name: cooling the clinker before it's milled. Improving cooler performance therefore has …

— The operation of the cement raw mill is a critical step in cement production. By grinding the raw materials into a fine powder, these powders can be more easily mixed with other cement ingredients and burn more evenly during the cement clinker process. Therefore, the efficient operation of the cement raw mill directly impacts the production …
— In cement plants clinker outlet temperature is directly evaluated by clinker cooler process efficiency. ... the clinker should be introduced to rapid quenching effects for improving clinker quality .

Durability of concrete made from cement is certainly determined by the clinker quality and composition. The clinker must be combined to a low residual free lime (<2.5%) and not contain more than 5% MgO. However, presuming adequate combination, the strength development of the cement made from the clinker is the primary measure of clinker quality.
