CLINKER GRINDING IN CEMENT PRODUCTION

Earlier we considered a mixture of which materials is used in cement production. The base of this mixture is a clinker. In this article, we will consider the composition of clinker and its impact on grinding balls deterioration in milling process. Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker

Cement mill - Wikipedia

The hardness of clinker is important for the energy cost of the grinding process. It depends both on the clinker's mineral composition and its thermal history. The easiest-ground clinker mineral is alite , so high-alite clinkers reduce grinding costs, although they are more expensive to make in the kiln.

Portland cement clinker

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
