Raw Mill In Cement Plant. 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
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 of the finished cement, and has a large effect upon the efficiency of the whole manufacturing process.
After monitoring and controlling the quality of incoming raw material, the area of high activity for quality department to ensure quality mix for smooth production of high quality of cement is “mill feeding system”. The system consists of material hoppers/bins, weighing, conveying, venting and mill feeding gate. Mill Feeding Hoppers
Raw mill is also called raw material mill, which is the essential equipment in the production process of cement. It has large application such as raw mill in cement plant, building materials, metallurgy, electric power and chemical industry, which is mainly used for the grinding as well as drying of cement raw materials and other materials.
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).
01-06-2012· Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials .While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction .

Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

In today’s modern cement industry, your competitiveness relies on being able to produce a high-quality product, at low cost. Optimal raw material blending and stockpiling, efficient fuel use, stable kiln operation and accurate analysis are all vital to your success. That’s where we can help.
In cement production, it pays off to be an early adopter of new technology. Industry 4.0 will reduce costs, increase the bottom line, and even help attract and retain talent. Boston Consulting Group recently published a report highlighting five areas where cement producers can benefit from Industry 4.0, so we called them up for a talk on the future of cement.
CEMENT MANUFACTURING PROCESS PHASE II: PROPORTIONING, BLENDING & GRINDING The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay. Now cement plant grind the raw mix with the help of
reported (Munthe, 2010) that cement industry could contribute approximately 10% of all anthropogenic mercury emissions. However, emissions are highly variable depending on the fuels and raw materials used to make cement. The industry has considerable experience in preventing and minimizing inputs of mercury to and controlling releases from kilns.
