clinker clinker grinding production cost
Clinker
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 quality depends on raw material composition.
The resulting clinker (rounded nodules between 1mm and 25mm across) is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition.
