Abstract
A product bed comminution high-pressure roller press wherein the problem of great recirculations of product material or, respectively, high product circulation rates caused, for example, because of reduced roller press pressures is solved employing little machine outlay. Two rollers (10, 11) are surrounded by a housing composed of two stationary lateral end walls (12, 13) between which a rotatably seated material conveying ring (16) that can be rotated is arranged for an internal product material circulation. The product material is admitted from the side through one or more openings (22) in one or in both housing end walls (12, 13) and the product material is discharged laterally through one or more openings (24) in the housing end walls (12, 13) via a discharge element (25) and/or via one or more discharge elbows (27).
