The vertical roller mill has the obvious advantages of a high yield and low power consumption and is primarily used in large-scale slag grinding lines [32]. However, the relationships among the type of grinding equipment, the product fineness and the application quality have yet to be systematically studied, which affects the accuracy of a ...

The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent. Manufacturers have countered this generally satisfactorily with pressure drops reduced by lower nozzle ring velocities and …

The electricity consumption per single vertical mill is basically 8–11 kWh/t, while the electricity consumption of the system is basically maintained at 14–19 kWh/t. Though this process is more energy-saving than that of the tube mill, it is difficult to further reduce its electricity consumption because it belongs to the air sweeping mill ...

The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.
