Comminuting and dispersing apparatus

An apparatus (100) for dispersing, in particular, liquid to semi-liquid substance mixtures and for comminuting particles and suspensions, comprising a batch container (110) having one or more openings (120, 121) for the introduction of the substances and one or more openings (130) for the discharge of the substances, and comprising a process chamber (140) having a rotor (150) and a stator (160), the rotor (150) being 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), characterized in that:

• the stator (160) has a working surface (161) which is arranged 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 arranged 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, and the process chamber (140) of hollow-conical cross section, in which the introduced substances are dispersed, comminuted and homogenized, is formed between the rotor (150) and the stator (160);
• the one or more openings for the introduction of the substances comprise a first opening (120) along the rotational axis (155) and one or more additional openings (121) between the first opening (120) and the process chamber (140);
• and
• the rotor (150) is divided into an upper and a lower part, the working surface (151) of the upper part of the rotor (150) having:
• a first portion along which the working surface is continuous with the working surface along the lower part;
• and
• a second portion along which the working surface is bent tangentially inwards relative to the rotational axis (155) from the first portion in an area of impact of the substances to be processed.
