Vertical Mill Calculations | Mill (Grinding) | Nozzle
The nozzle ring area is the free area, perpendicular to the direction of the gas flow, as measured at the shortest distance between the table and the air guide cone: The gas velocity in the nozzle ring will normally be in the range: 35 50 m/s. The higher the velocity, the less material falls through the nozzle ring. Mill internals _ Dam ring
