Reply privately Flag as inappropriate Flag as promotion. HabiburUnfollow Follow HabiburThe VRM is a type of grinding mill that uses a vertically oriented, multi-level cylindrical roller to grind materials into extremely fine powders. The key components of a VRM are the grinding rollers and the grinding table. The grinding rollers are hydraulically loaded and held against the grinding table by means of hydraulic cylinders.Vertical Roller Mill in Cement Plant Ball Mill for Sale

VRM has been a more compact unit is quite smaller about the ball mills thus significantly reducing civil engineering cost about a ball mill plant. Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. TheThis 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 Minerals Free Full-Text Analysis and Optimization of
