These additives, along with the limestone, are fed from bins to the raw mill. An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct “blend” of these materials.

Modern Processing Techniques to minimize cost in Cement
The Horizontal/ Ring Roller Mill is a recent development in grinding. The mill has been developed by FCB, France (trade named Horomill) and FLS, Denmark (trade named Cemax Mill). Horomill is suitable for grinding raw meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and finishGrinding at both ball and for Raw Mill vertical mills CeMAx RM Grinding Aids Dosage 0.03%–0.10% Mill Output Improvement upto10% Recommended for both ball and vertical mills Improved coal/ petcokefineness and Particle size distribution CeMAx Cl Grinding Aids for Coal Mill for Coal/Petcoke grinding High Performance Grinding AidsFosroc Grinding Aids and Performance Enhancers

OK™ Raw and Cement Mill FLSmidth
Our vertical roller mill offers optimum raw, cement and slag grinding. Our best-in-class OK™ Mill is a globally successful vertical roller mill solution for grinding raw material, cement and slag. Its cutting-edge design features consistently deliver the highest quality products with the greatest efficiency. It is affordable to install andcement. Hence, one grinding compartment will generally suffice. For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners. If the raw materials are particularly coarse, a mixed solution might be best. This could be either by replacing the first few rings e.g., the firstIG PERFORMANCE PARTS Mill Liners for Ball Mills

As far as we know, there are few multi-objective optimization studies on energy consumption and grinding energy efficiency for a VRM. There are usually four kinds of VRMs in the cement production line, including raw meal mill, coal mill, Clinker Mill and cement mill, and the vertical mill occupies a large energy consumption unit.Vertical roller mills have a smaller footprint, are more compact, and easier to install, making them ideal for smaller and medium-sized cement plants. They also offer better flexibility, allowing for the easy adjustment of product fineness and production rate to meet changing market demands.

40 CFR Part 63 Subpart LLL eCFR :: Home
In-line kiln/raw mill means a system in a portland cement production process where a dry kiln system is integrated with the raw mill so that all or a portion of the kiln exhaust gases are used to perform the drying operation of the raw mill, with no auxiliary heat source used. In this system the kiln is capable of operating without the raw mill operating, but the raw mill Kaiserslautern-based Gebr.

Review on energy conservation and emission reduction
Electricity can be saved if raw materials and coal are ground in advanced roller mills like horizontal, high-pressure, and high-efficiency roller mills. If a vertical/horizontal roller replaces a traditional ball mill, the energy saving is estimated to be 6–7 kWh/ton of raw materials (Madlool et al., 2012).in raw material IN and OUT of Coal mill is 7-12% and 2.2-3.5% respectively as per plant data.
