vrm or ball mill for cement grinding

VRM or Ball Mills For Cement Grinding

The century-old ball mill and the more recent, Vertical Roller Mill (VRM). There has been professional, academic, and technical debate as to which grinding mill technology is better. Most claim VRM to be better, yet majority of cement producers still use the BALL MILL FOR CEMENT GRINDING. For comparing the two, these criteria are usually considered — cost and ease of installation, cost and ...

Ball Mills Or Vertical Roller Mills: Which Is Better For ...

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. The equipment cost is, however, higher for a VRM than a ball mill.
