Abstract
Impact mill comprising a housing (1) wherein a drivable centrifugal rotor (3) rotatable about a rotational axis (8) and an impact body (7) enclosing this centrifugal rotor are provided. At least one sensor (11, 111, 211, 311, 411) is assigned to the impact ring (7), which sensor functions during the operation of the mill and which is designed for detecting at least the operational efficiency, preferably also for determining the extent of the wear of the impact ring (7). The sensor (11) senses the impact body (7) through an opening (12) in its annular or cylindrically-shaped housing (13).
