There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of …
1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In …

The process is called a drying /grinding process, where most of the material/product is transported pneumatically by drying gases. ... Development of the continuous silo concept started with the introduction of raw material preblending systems in the cement process out of the need to reduce power consumption for cement raw meal homogenization ...
The crushed raw ingredients are made ready for the cement-making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. …
consumption is used for grinding. In optimising the process, the grinding tools will have a significant impact on lower production costs as well as maintenance costs. Ball mills and grinding tools Cement ball mills are typically two-chamber mills (Figure 2), where the first chamber has larger media with lifting liners
PPC is produced by the inter-grinding and blending of 65% clinker with 30% fly ash and 5% gypsum to a fineness of 320 m 2 /kg. Fineness is a controlled parameter for cement to ensure better hydration and strength development. Ground cement is then stored in a water-proof concrete silo for packing. More ++
