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
