Slurrying apparatus including grinding and separating means

A slurrying apparatus comprising a rotatable drum arranged for rotation about its longitudinal axis and including a slurrying chamber portion so arranged that when said drum is rotated, feed material passes from an inlet of said slurrying chamber portion to a discharge portion of said drum wherein slurry and fine particles are separated from coarser particles and are discharged separately, said slurrying chamber portion including means for grinding or pulverizing solid particles, said slurrying chamber portion being lined with a plurality of liner assemblies each including one or more scoops extending substantially parallel to the longitudinal axis of said drum, said scoops supporting one or more comminuting bars extending substantially transversely to said scoops and arranged to form a grid spaced inwardly from the internal surface of the drum, and means for causing rotation of said drum.
