A rotor/stator apparatus is proposed, with a bearing block, a casing (1), a rotor shaft mounted therein, on whose end directed toward the casing a rotor designed with a conical surface has been secured, there being a stator (2) secured within the casing and concentrically associated with the rotor, where those surfaces that face toward one another of the rotor (2) and of the stator (3) form a gap upstream of which there is an axial feed neck and downstream of which there is a radial outlet neck, where rotor and stator have been mounted so as to be capable of axial shift in order to form a gap with adjustable gap width, wherein one or more holes extending to the exterior has/have been provided in the region of the feed aperture of the rotor/stator apparatus in the feed line prior to and very close to the rotor/stator apparatus and/or in the casing (1) and/or in the stator (2), and alongside the outlet aperture at least one further hole has been provided in the annular space around the shear gap. A process is moreover proposed for the salt-free coagulation of polymer dispersions, utilizing the rotor/stator apparatus described above.
