An apparatus for removing liquid from a composite mixture of liquid and soli ds has a hydraulically operated ram 208 that compresses the mixture into snout 12 and extruder 14 sections. Under pressure from the ram 208, liquid in the mixture escapes from numerous drainage slots 25 in the snout section top, bottom and sides 2 4, 22, 20, and the extruder section top, bottom and sides 30, 28, 26. A platen 80, pivotally mounted to the extruder top plate 30 near the exit of the device and biased with a constant pressure, controls the back pressure in the extruder and snout sections 14, 12. The slots 25 have cross sections that diverge from an inner surface to an outer surface of the walls.
