The mill has a housing (39) surrounding a working chamber (30), and a material inlet (31) for putting materials into a milling device (42) from top. A material outlet (38) outwardly leads to an upper region of the chamber, and a reverse feed downwardly leads to the milling device. The milling device is a centrifugal spinner disk (32) rotatable in a horizontal plane, where the disk works together with an impact shell (35) arranged in the housing. A nozzle ring (45) surrounding the disk from bottom supplies fuel gas into the chamber. An independent claim is also included for a method for milling of powdery or fine-grained material such as gypsum. |
