    Patent number: 9174218
    Abstract: An apparatus (100) has a batch container (110) having one or more openings (120) for the introduction of the substances to be processed, one or more openings (130) for the discharge of the processed substances, and a process chamber (140) having a rotor (150) and a stator (160), the rotor (150) mounted rotatably about a rotational axis (155) with respect to the stator (160) for the purpose of processing substances introduced into the process chamber (140). The stator (160) has a working surface (161) which is inclined at an angle W1 in relation to the rotational axis (155) of the rotor (150) and the rotor (150) has a working surface (151) which is inclined at an angle W2>W1 in relation to the rotational axis (155) of the rotor (150), such that the working surfaces (161, 151) of stator (160) and rotor (150) are disposed at an acute angle relative to each other.
