CONDITIONING DRUM FOR USE IN HOT WATER SEPARATION OF BITUMEN FROM MINED TAR SANDS Abstract of the Disclosure A rotating drum type muller is described for initial conditioning of mined tar sands by the hot water method for separation of bitumen from the sands wherein ablation of mined tar sand lumps into pulp is effected through the addition of hot water, steam and caustic. This conditioning drum comprises a horizontally disposed cylindrical drum of a length to diameter ratio of about 1:1 or less, rotatable around its longitudinal axis and having axial openings at its inlet end for introduction of mined tar sand lumps; water and caustic and at its outlet end for rejection of oversize and discharge of mulled tar sands pulp, said axial opening at its outlet end being divided by a coaxial grate member, extending along the longi- tudinal axis of the drum, into an outer annular opening for discharge of tar sands pulp and an inner axial opening for rejection of oversize, said grate size being sufficient to allow ready passage of tar sands pulp into a discharge passageway defined by the outer annular opening while remaining the oversize; and a plurality of downwardly projecting steam conduits affixed to a stationary steam header extending substantially over the length of the drum interior along the longitudinal axis of the drum, said conduits being perforated for injecting steam into said cylindrical drum. - 1 -
