<p>A rotary impact mill has a rotor assembly (1) in which impact elements (7) arranged in at least two axially spaced rows provide, or can be adjusted to provide, a grinding gap ( a ', a "), defined between the impact elements and the inner (grinding) surface of the mill housing (2), that is not constant in the axial and/or circumferential direction of the rotor assembly. Impact elements can be fixedly or adjustably mounted in the rotor assembly and/or, in a conical impact mill, the rows can be mutually adjustable axially to change the grinding gap.</p> |
