Figure 2. VRM Production Rate and Specific Power It can be clearly seen in Figure 3 that last 6 months average breakdown frequency Rate was 60.16 tripping per month means per day more than 2 tripping. Excess breakdown results in frequent start/stop of VRM which consumes more power & also stability of Mill operation and productivity gets affected.
Review on vertical roller mill in cement industry & its …
Vertical roller mill. The feed is ground by pressure and friction between the horizontal rotating table and 4 to 6 grinding rollers in the VRM. These rollers are hydraulically pressed against the table as shown in Fig. 3. To enhance grinding operation, the rollers and axes of the table should not move through the plane of the table.

VRM components are subject to severe wear. This is particularly true when grinding materials with high silica content and slags, such as are found in cement mills. This wear has a direct impact on a plant's bottom line: a worn VRM roller reduces grinding efficiency, increasing the energy demand and costs of milling.

A Technical and Economic Comparison of Ball Mill …
A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of 39.2% was observed for the dry VRM compared to the wet ball mill (37.7% for the circuit).
VRM – THE LATEST TECHNOLOGY – Bashundhara Cement
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.
