Coal utilisation in the cement and concrete industries. G. Schumacher, L. Juniper, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013 15.3.1 Make-up of Portland cement. Portland cement is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of gypsum (calcium sulphate dehydrate – …
Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical ...

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 …
In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of cement rotary kiln, clinker cooler (also called cement cooler) is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas.It plays an important role in the cement …
As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...
The Importance of Clinker in Cement Production. The substance called clinker is dark gray as the color that appears after firing while cement is produced and it is called the material that resembles the …
Clinker kiln (cement kiln or cement rotary kiln) is the main equipment of cement plant. The clinker is formed by calcination in it. During the calcination process, raw meal powder is fed into the kiln cylinder from …
