Abstract (en)

[origin: DE19824806A1] The invention relates to a pulper device comprising a vessel (1) in which an annular flow can be generated. Said flow acts upon a liquid-solid mixture located inside said vessel (1) and effects a pulping of the same. Said device also comprises a screening device (4) for separating course materials from the suspension, whereby the screening device (4) has the shape of a truncated cone. Said truncated cone is provided with holes on the lateral surface thereof and can be mounted on the base of the vessel (1) in such a way that the truncated cone points upward with the small circular surface thereof, and the lateral surface lies in an approximately tangential manner to the toroidal flow. The screening device (4) is subdivided into different segments and these segments can be individually mounted from the external side of the vessel.
