Even if cement is a well-consolidated material, the chemistry of cement (and the chemistry inside cement) remains very complex and still non-obvious. What is sure is that the hydration mechanism plays a pivotal role in the development of cements with specific final chemical compositions, mechanical properties, and porosities. This Cement grinding aid is a kind of material which can promote cement grinding, and it is an important part of energy-saving development of industry at present.

Energy utilization of the cement grinding circuit was improved by 4.3%. Changing the flow sheet may lead to improved energy efficiency however care must be taken regarding to the product specifications since it is the main concern of the whole manufacturing process. Within the study, as the focus was given on direction of the filter Chemical process industries are running under severe constraints, and it is essential to maintain the end-product quality under disturbances. Maintaining the product quality in the cement grinding process in the presence of clinker heterogeneity is a challenging task.

Introduction. Cement world production currently increases up to approximately 4 billion tons/year. The electrical energy consumed in cement production is 110 KW/tone and about 30% of which is used for raw material preparation and about of 40% for final cement clinker grinding [1], [2], [3].This leads to important cost increase of the Introduction. Cement industry has been struggling with issues of demand and supply gap, high energy consumption, high CO 2 emission that all have effects on the sustainability of the manufacturing process. However, it is still the key component of the buildings and its rate of production is expected to rise between 12 and 23% by 2050 The impacts of dry stirred milling application on quality and
