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.
The vertical roller mill VRM is popular and widely used for grinding of coal and raw materials. The vertical mill is energy efficient with low specific wear rate. Vertical mill supports drying of the feed material, grinding, separating, and material transport inside the mill.
Cement plants are usually designed with raw material grinding systems with low energy consumption, especially the vertical roller mill VRM, which is the first choice for large cement plants. Due to the large power consumption of large cement plants, the use of vertical roller mill can obtain obvious power saving effect.
Aug 17, 2020 1.5.3. Vertical Roller Mill VRM Vertical roller mills VRMs with integrated classifiers have been used successfully for many years in cement plants to grind and dry raw materials simultaneously with moisture contents up to 20 by weight. Their production can be as high as 400 tons per hour, and they have a drive power of 11.5 megawatts .
It is known that the largest area of energy consumption in manufacturing cement is in the finish milling process. Consequently, such wear problems can significantly influence the profitability of a plant. A worn VRM roller profile also reduces grinding efficiency, increasing energy demands further.
