ABSTRACT:
A device for separating the liquid phase from the solid phase of rigid multiphase materials such as bituminous schists, domestic waste and vegetables, in which there is used at least one compression operation at a pressure of at least 500 bars, the compression being effected in at least a first elongated chamber (2) having orifices (4) adapted to let the fluid materials pass, a pressure being applied at an inlet end (1a) by a piston (3), the volume of the chamber exceeding the volume swept out by the piston so that the compressed material remains under pressure in the chamber during several strokes of the piston, the other end (1b) of the chamber being equipped with an extraction-metering system (5) so as to allow the permanent pressure of the material in the chamber.
