The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
Vertical roller mill(VRM) and clinker grinding mill and other cement grinding mill are also very common in cement plant. Cement mills and raw mills for high throughput rates. The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill.
Rebuilding of Vertical Roller Mill [VRM] Rolls amp; Tables Vertical Roller Millsl are a special grinding equipment, used by Cement Industry and Power Industry [Carbon Fired Plants] by its high energy efficiency at low cost.
Vertical Roller Mill (VRM) is the most advanced technology in cement production procedure. Bashundhara Cement has adopted VRM from LOESCHE, Germany in both the factories to ensure the best quality. With higher fineness achieved with VRM, it creates stronger and better quality concrete and thus, proves its superiority over other cement brand.
PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL . Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM The conventional control system of VRM composed of field staff to adjust the few process parameters manually with their experience, it leads the system unstable, high power consumption and low productivity.
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated

Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
The FL vertical roller mill (VRM) was chosen to produce a full range of cement types at the Muktarpur Plant. Driven by two MW FL MAAG Max Drive gear systems, the impressive mill is the biggest VRM ever to be installed in a cement plant in
