and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.

The benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland …
control technologies and measures presented in this document focus on this pollutant. While a large number of available technologies are discussed here, this paper does not necessarily represent all potentially available technologies or measures that that may be considered for any given source for the purposes of reducing its GHG emissions.
Keywords: Cement grinding aid, Fineness, Compressive strength, Size distribution. Abstract. In this paper, By choosing four kinds of grinding aids better one-component, The grinding aid of cement grinding aids is determined by orthogonal optimization. By adding different inorganic reinforcing components, Developed a cement grinding
Generally, cement's initial strength is enhanced by improving the fineness of the product but the long-term strength is not enhanced. Therefore, excessive fine grinding should be avoided even to prevent waste of power. In cement production technologies, the recently spread roller mill
Blended cements can be produced in two ways: by intergrinding the components or by separate grinding and mixing them. With the intergrinding process all components of the blended cement are ground together. In that way the cement is homogenized during the grinding, and at the concrete plant only one silo is needed.

In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C.
In the cement industry, one of the main topics is reducing the energy consumption. In the cement manufacturing process, cement grinding accounts for approximately 40 % of the specific electrical energy requirement. Two-compartment ball mills operating in closed circuit comprise the primary technology for grinding cement.
The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength, (Fig. 3). The fineness of grinding has increased over the years.
