ABSTRACT:
A drying mill for powdered or fine-grained material, in particular also suitable for calcining gypsum, employs a housing, in which a feed device for fuel gas, opening into a lower region, a comminuting device and a material inlet, charging the material onto the comminuting device from above, are provided one above the other, a material outlet leading to the outside from an upper region of a working chamber and a return leading downwards to the comminuting device, the comminuting device being a centrifugal disc which rotates in a horizontal plane and interacts with an impact casing arranged on the inside of the housing. A nozzle ring surrounding the centrifugal disc from below is provided for feeding fuel gas into the working chamber. As a result, the calcining process in particular is assisted in an efficient way by utilizing the thermal energy of the hot gas fed into the working chamber by means of the nozzle ring and the dwell time in the working chamber. A corresponding comminuting method is provided.
