Application of ESP is studied, keeping in view Indian conditions. The characterisation of dust emissions has been done for different units, such as rotary kiln and raw mill, alkali by-pass, clinker cooler, cement and coal mill, in terms of exit gas quantity, temperature, dew point, dust content and particle size.
Cement industry is not a water polluting industry. Only the cooling tower blowdown associated with the GCT is a source of waste water generation, which does not have much significance as a water pollutant. The waste water is treated in septic tanks or sewage treatment plants and is used for gardening, irrigation and other purposes.

Mar 01, 2018· A Norwegian cement plant producing about 1.3 million tons of cement per year was used as a case study. A mass and energy balance was made for the raw meal department, and process data available from the plant process database as well as manually measured gas flow rates were used to calculate the available heat.
Sep 12, 2019· C15 transferred the raw materials to the vertical roller mill (VRM) as the raw materials should be finish-ground before being fed into the kiln for clinkering. This process is done in the VRM. The raw materials are simultaneously dried using hot air in order to get good quality cement.
raw mill esp dust emission very high. Dear sir, i am taking hot gas for vrm from preheater outlet, preheater duct is also conected in (gct) gas condictioning tower and their is also spreing water. if vrm is running it is ok emission. but if vrm is not running any reason then emission is …

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...

samples were collected to analyze the Hg mass balance. The total Hg concentrations in the raw mill electrostatic precipitator (ESP) input of the two plants were 155.70 and 64.62 µg Nm–3, respectively, which were higher than those at any other sampling point. Approximately 97.5 and 86.5% of the Hg in the raw mill ESP input at Plants 1 and 2,
Mercury emissions are typically higher in kiln operations with the raw mill-off ("direct" operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
