Abstract (en)
[origin: EP0364205A2] An apparatus for refining moldable ceramic batch bodies is provided within a molding cylinder (1) upstream of a molding die (8). The refining apparatus comprises a screen (2) and a screen supporting perforated plate (3) having a plurality of body passages (9) therethrough. To avoid inclusion of air in the molded product due to separation of the noodles emerging from the perforated plate (3), each body passage (9) is tapered to diverge towards the body chamber (5) defined between the molding die (8) and the perforated plate (3). Thereby the noodles extruded through the passages (9) are urged towards each other by a component of force in the direction perpendicular to the extrusion direction.
