Larger gear drives for larger vertical roller mills

Whereas machine design is often the limiting factor for large ball mills and roller presses, it is the drive systems that require focus in vertical roller mills (VRMs). Placing silos before and after the kiln can reduce short interruptions in the milling processes, but long standstills caused by unexpected mechanical failures are difficult to avoid. Reliability of VRMs depends on the drive

Cement grinding Vertical roller mills versus ball mills

vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the vertical roller mill
