Abstract
The invention relates to the extrusion of particulate materials having excess liquid, which must be drained off during extrusion in an extruder having a shaping part comprising a first part 2 for defining a first surface and a second part 1 for defining a second surface on the extruded part 6c, in which the shaping part 1, 2 has sub- sections 1.1, 1.2, 1.3 and 1.4 for the introduction, moulding, draining and compacting of the said materials, so that the extruded part 6c leaves the final friction section 1.4 in a dimensionally stable condition. According to the invention the shaping section 1.2 of the extruder has a closure 14 opposite the friction section 1.4, the introduction section 1.1 is a cylinder 9 with plunger 10 for introducing the suspension under pressure into the shaping section 1, 2, and the friction section 1.4 has a brake member 15, displaceable in the longitudinal direction of the extruder and having a removable closing plate 18. The characteristics of the finished product 6c are thereby significantly improved in relation to those in the case of a known method and apparatus. <IMAGE>
