Our clinker grinding to cement composition of raw materials

Clinker quality depends on raw material composition.


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. If the raw materials are inappropriate, or if they are blended improperly, buildings and roads made from the concrete will have poor strength and durability.

Raw Material Preparation


This meant that, for the first time, there was virtually no limit on the fineness that could be achieved. From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding.

Portland cement clinker - Understanding Cement


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.

Portland Cement Clinker - an overview | ScienceDirect Topics


The sintering of Portland cement clinker is simply called "twice grinding and once sintering", that is, grinding the cement with cement raw material; sintering the calcined part of the raw material into clinker; grinding the clinker with a limited amount of gypsum into Portland cement clinker. The sintering process of Portland cement clinker is shown in Figure 4.1.
