In this study, the engine studied was the Raw Mill machine at plant. The raw mill machine functions as a main material grinder in the initial milling process such as limestone, silica stone, claymaterials as fed to the raw mill are effectively dry, silos are appropriate for the feed materials. Where wet materials are fed for drying in the raw mill, silos are unnecessary. Ball mill operation is described in more detail under finish milling (Section 5.2). Roller mills have a lower specific power consumption than ball mills.Cement Plant Operation Handbook PDF Mill (Grinding)

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on The mill feed material needs to be free of metal pieces. Higher the metal pieces frequent operation of diverting gate and results in feed variation. [8,12,14] Abnormal feed size and distribution may increase the level of vibration and destabilize the mill. Large feed size in any case will reduce the mill production rate. Excess fines in the feedIndicate Contributions from Several Radial

and vertical roller mill i.e., VRM [3–5]. Among these devices, VRM plays an important role in cement, accounting for more than 55% of China’s cement raw meal market [6], and its performance directly affects the cost of producing cement. VRM has the functions of grinding and powder selection, including a grinding unit and an air classifierliners that optimise your coarse grinding operation or corrugated and classifying liners that improve fine grinding, we have the right liner for every grinding application. And with more than a century of experience in ball mill grinding, we can help identify the optimal combination of liners for your operation even for non-FLSmidth mills.IG PERFORMANCE PARTS Mill Liners for Ball Mills
