A schematic diagram of the raw mill system in a cement plant is illustrated in Fig. 1. In this process, raw materials, such as CaCO 2, SiO 2, Al 2 O 3, Fe 2 O 3, MgO, K 2 O, SO 3, and Na 2 O at the reference temperature and pressure enter the raw mill system to produce farine.
Cement kilns, with their high flame temperatures, are sometimes used to burn waste oils, solvents, and other organic wastes. These practices can result in the release of toxic metals and organics. Cement plants are not normally designed to burn wastes; but if such burning is contemplated, the technical and environmental acceptability need to be
Grinding of cement raw material – material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm).
The quality of cement can be compromised by the conditions in the mill system and cement silo. But improving silo conditions is a complex and expensive process. As an industry leader in cement grinding and high-quality cement production, we help cement plant operators produce silo-safe cement.

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.
The study indicates that for a dry type cement production process, the carbon dioxide emission intensity for kiln feed preparation process is about 5.4 kg CO 2 per ton cement produced. In this study, the raw mill of a cement plant is considered and its performance based on the first and second laws of thermodynamics is investigated.
