Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind. Rapid cooling of the clinker is thought to improve grindability due to the presence of microcracks in alite and to the finer ...

to conventional grinding plants. But on the other hand, standalone grinding plants are strongly dependent on locally sourced raw materials, as well as clinker, which is subject to extensive transport and multiple trans-shipments. This may result in variable quality, seasonal moisture content, and more dusty and fine clinker.

Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

A clinker grinding station is finished production in the last stages of the formation of a separate and independent production unit of finished. This phase will add the right amount of mixed clinker material regalia, output finished. The production generally can be divided into raw material preparation, clinker and made rum the three processes.

The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color.
