Abstract
A size reduction device and method for solid particles, which are conveyed as a suspension in a liquid flow. The device includes a housing, at least two counter-rotatable size reduction components disposed in the housing, each including a plurality of cutting elements, disposed on a common rotatable shaft with a longitudinal axis. The flow direction of the suspension is at right angles to the longitudinal axes of the shafts of the size reduction components. Two mutually opposite guide rails with a longitudinal axis parallel to the shafts are assigned to components. Each guide rail includes a base plate, on which ribs with channels are constituted parallel to the flow direction on the side of the base plate towards the component.
