An air vortex mill ( 1 ) mill dries a flowable product in a gas-/air flow-through grinding chamber ( 3 ) with several grinding stages arranged in the grinding chamber. The grinding stages are formed by a rotor ( 4 ) with a multitude of grinding plates ( 9 ) and a stator housing. A device ( 12, 13 ) delivers preferably heated carrier gases, as a device ( 6, 15, 16, 18 ) delivers the product into the grinding chamber ( 3 ). In order to improve the product delivery to the mill ( 1 ), one component of the delivery device is a supply line ( 6 ) which encircles at least part the circumference of the grinding chamber ( 3 ). The supply line ( 6 ) is equipped with an inflow ( 15 ) for the product to be treated and a plurality of outlet apertures ( 18 ) distributed over the circumference of the grinding chamber, for delivering the product into the grinding chamber.
