In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered. As a general rule, the size of media has to match the size of material being ground: large media can't produce the ultra-fine particles required in the finished cement, but small media can't break

Correct timing on the maintenance of a first chamber cement mill lining and the successful implementation of an expert system on a cement mill both offer benefits in terms of power consumption (see case studies panel). Accurate process measurements are also key to energy saving opportunities. Air compressors are another area for attention.

cement mills and the auxiliary equipment take the major share in the electrical energy consumption. Summary of the electrical and fossil fuel (thermal energy) flow in cement production is presented by Madlool et al. [7]. Out of the 75% thermal energy consumed in the cement production process [13], 35% of it is lost to the environment as waste heat

The flash chamber width is the dimension of the chamber across the flow of the brine. The shell load is the mass flow rate per unit width of the flash chamber in kg s-1 m. The stage distillate production rate is the mass flow rate of the vapor leaving the brine in the stage. This vapor will condense on the heat transfer area in the upper section

The raw mill contains two chambers, separated by diaphragm, namely a drying chamber and a grinding chamber. The hot gases coming from a preheater (preheater kiln system) enter the mill and are used in raw mills for drying. Then the drying materials enter the grinding chamber of raw mills for fine grinding.
Net Heat Input (NHI) is the GCV of the fuel minus the radiation losses, loss due to unburnt combustible, moisture in air, latent heat of moisture in fuel & that formed by combustion of H2 in the fuel plus the sensible heat of combustion air (Primary plus Secondary air), all above reference temperature.
Heat imparted to the material, due to the work of grinding, is related to the time it is held within the chamber and the air flow characteristics. Impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake.

Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the dashes indicating

Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal. • Other methods like Macarel analysis is also used
“natural” mill camber. g. Heat cambering should be performed only on low-carbon steels. Application of heat to medium-and high-carbon steels increases the danger of embrit-tlement. ASTM A36, A572 Gr. 50, A588, A441, and A242 are popular low-carbon steels. [Note ASTM A992 is also a low-carbon steel.] h. When using the heat-cambering
dried material is gradually transferred to the grinding chamber. In the grinding chamber the material is grinded with the help of grinding media balls. In the 3 rd stage the heat and 4 th is about 500 to 600 oC and 350 oC to preheater is diverted back to the raw mill for drying the raw material. The balance
