An apparatus for processing oil sand to produce a liquid stream comprising water and bitumen and a solid stream comprising solid particles. The apparat us includes a drum comprising a conditioning zone, a compressing zone and a processing zon e. A rotatable spiral trough, having lifting members therein, extends through eac h zone for imparting a spiral rolling motion to the oil sand. An oil sand inlet communicates with the conditioning zone, while a water inlet communicates with the processing zone . A liquid stream outlet is located at a first end of the drum, while a solid stream outlet is located adjacent a second end. The solid stream outlet is comprised of the drum defining a plurality of perforations which provide a screen section. The perforations are sized s o that the solid particles having a size less than or equal to a desired maximum size may exi t the drum through the perforation.
