11· The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •The difference between vertical roller mill and ball mill,of the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%90% Vertical mill process features: (1) The structure is simple, the vertical mill
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.Comparison Of Vertical Roller Mill And Roller Press Mill,When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 78kWh/t. But the vertical mill is usually slightly higher. The system of the vertical grinding mill is simple and stable.
The VRM's are even more powerful since the work is not so big (due to the working principle the VRM has no to lift such huge grinding media) and therefore throughput is bigger and the installed power is much more used than in a ball mill,Use Fly Ash Ball Mill Make Flyash Cement ball mills supplier,This ash ball mill is an optimized design for the characteristics of fly ash. Compared with ordinary cement ball mill, it is more suitable for treating fly ash with uneven ash content. Ordinary cement ball mill is mostly used in circulating grinding system, and the effect is more obvious for grinding slag cement.
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.. VRM vs Ball Mill for Cement Grinding Page 1 of 1,210· VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.
