Mill internals _ Nozzle ring 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.

The grinding air is injected tangentially via Laval nozzles in the nozzle ring into the machine. This causes a spiral jet of air to form in the grinding zone, from which the mill derives its name. A high pressure forms in the mill as a result of the spiral flow of air that can rise to 1 bar overpressure in operation without product.
