Abstract

Defined energy powered mill of the confined vortex type for drying and grinding a suspension of powdery solids, including said mill; a generally circular grinding chamber defined by a pair of opposite axial walls and a peripheral wall, a suspension feeding device consisting of: walls that define a generally rectilinear duct that opens in a peripheral region of said chamber, a suspension supply conduit having an inlet port remote from said conduit and a discharge nozzle arranged in said conduit to direct the suspension along the conduit and towards said chamber, the size of the discharge nozzle being small relative to to the duct that surrounds it to define an annular space between these elements, means for supplying a gaseous drying fluid at least at the speed of sound to said annular space in order to wrap and atomize inside the conduit the suspension that comes out of said discharge nozzle, means for controlling the temperature of said discharge nozzle, and discharge means for extracting the powdery solids and the gaseous crushing fluid along the axis of the chamber.
