Pulverizing apparatus, known as hammer mills, for crushing rocks, etcetera, are known, which use swinging hammers, pivotally mounted on a rotating axis within a casing. The present invention provides a crushing apparatus comprising a housing with first and second cylindrical chambers, the first chamber having an inlet for input of material to be crushed, and the second chamber having an outlet for expulsion of crushed material. An axle is mounted for rotation in the housing and provided with means for rotating the axle. Hammers are mounted for rotation in the first chamber. Blades are mounted for rotation in the second chamber and have a flat surface for moving air in the second chamber. A flywheel is mounted for rotation on the rotating axle and forms a central wall between the first and second chamber while being adapted to leave a clearance between the first and second chamber sufficient for movement of crushed particles.
