  • Vertical roller mill optimisation

    Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding drying classification and regrinding

  • Cement grinding Vertical roller mills versus ball mills

    The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the 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
