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 mills regardless of size and application.
Applicability of oxy-fuel technology to clinker burning process • Oxygen production by air separation is state of the art (by freezing or membranes) • Oxy-fuel technology is state of the art in other industries, e.g. for glass production • New combustion technologies required, e.g.: – Oxy-fuel burner – Waste gas recirculation
The raw is then fed to the coal mill VRM via weigh feeder, drag chain and screw conveyer. Important Parameters Of Coal: • Residue on 90 micron=18-20% • Residue on 212micron=0.4-1% • Moisture =1.5% • Volatile Matter =20-30% • Ash content =28-32% Coal Mill:Coal Mill is an important integral part of cement plant.
Figure 3.1: Typical Mimic sample of the Raw Mill Section 4. ENERGY SCENARIO 4.1 Electrical Energy System The cement plant receives electricity supply from the Captive Power Plant (CPP) (12 MW) and DG sets. It is distributed to various sections of the plant. An energy meter is installed on 110 kV feeder incomer, which records
processing units are crushers unit, raw mill, homogenizing plant, kiln system, cement mill and packing plant. Here, dry production process is used because energy consumption is less and running cost is also lower compared to other process. The raw materials used are in the following compositions; limestone 95-97% and laterite 3-5%.

Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement.
The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...
The raw mill in a cement production plant has also been investigated in relation to exergy analysis. The work performed an energy and exergy analysis of a raw mill and raw materials preparation. The results obtained for the energy and exergy efficiency of the raw mill were 84.3% and 25.2% respectively.
A modern dry process cement plant, with efficient configuration of the grinding and pyroprocessing systems typically consumes less than 700 kcal/kg-cl thermal energy and 100 kWh/mt of electrical energy. Cement plants are designed based on the raw materials and fuel samples tested by the equipment supplier.
Raw mill in running condition in cement plant Real view, how raw grinding done in cement industry
The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

vi Improving Thermal and Electric Energy Efficiency at Cement Plants: International Best Practice Cement is paramount for economic development and poverty reduction in emerging markets. Along with aggregates and water, cement is the key ingredient in the production of concrete, and, as such, is an essential construction material
So, the raw mix is burnt to produce clinker : the basic material needed to make cement. conveyor Raw mix kiln cooling preheating clinker storage at the plant Raw mill 13. THE CEMENT MANUFACTURING PROCESS 1.GRINDING : The clinker and the gypsum are very finely ground giving a "pure cement".
In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
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.
cement plants are located close to a calcareous raw material source whenever possible. Other elements ... Cement raw materials are received with an initial moisture content varying from 1 to more ... water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of ...

The results show that approximately 2.48t, 4.69t, and 3.41t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages ...
cement industry has been using large quantities of waste fuels or biomass fuels, for more than 15 years. The production of cement involves the consumption of large quantities of raw materials, energy, and heat. Cement production also results in the release of a significant amount of solid waste materials and gaseous emissions.
The milling process in cement plants is extremely energy-intensive. there are potential energy savings available through the use of Mill Control System (MCS). The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values).
