Abstract (en)

Formable material such as pigment filter cake is extruded in filamentary form for drying by means of a ram extruder which eradicates local zones of inhomogeneity. Pressure may be applied by the ram in two stages; a lower pressure to homogenise the material followed by a higher pressure to extrude it. Apparatus for carrying out the process comprises container transportable in cage between a loading/unloading station and an extrusion station.
