A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part ,discharging part ,rotating part ,transmission part(reducer,samll transmission gear ,motor,electric control) etc.
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 efficiency of the whole manufacturing process.
Working principle of raw material mill. The cement raw mill is generally cylindrical in the horizontal direction, and gears are driven at both ends. After the motor is turned on, the cylinder is rotated. Raw materials are evenly fed into the first inner silo from the feed port at one end.

Raw Mill In Cement Plant,Cement Making Plant. This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder.
As part of the implementation of the 5,000 tpd cement production line for Qatar National Cement Company, Fives installed the 6.6 MW FCB B-mill of the raw meal grinding plant in March 2017. Installation of the raw mill shell, weighing 198 tons for 17.2 meter length and 6.4 meter diameter, was carried out successfully on March 29, 2017.
Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. Induced Draft Fans.

Raw Mill in Cement Plant is mainly used in grinding Cement finished products and Raw materials, applies to the metallurgical, chemical, electric power and other industrial and mining enterprises all kinds of ores and other materials grindability. Can be used to open stream grinding, also apply to and classifier composed of grinding cycle flow.
Mr. Subrata Bhaumik has more than 50 (Fifty) Years (1965 2016) of Experience in Cement and other related Industry covering more than 100 assignments in cement plants with capacities ranging from 100 tpd to 10,000 tpd in India and abroad involving visit to 25 countries overseas in connection with work.
2. Raw meal production The crushed limestone is ground into raw meal. Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then homogenised in the blending silos.

Raw Mill Exhaust Fans. Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill’s modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller

Aug 30, 2012· Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.
Cement plants form a challenging environment for rotating equipment. Significant amounts of silica dust occur as a by-product of certain construction processes. Over time this dust subjects rotating equipment, including Raw Mill fans, to high levels of erosion which ultimately reduces the plant’s output over time.
In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Pre-homogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.
