A method and apparatus for efficiently separating solids from liquid/solid slurries are disclosed. The slurry to be separated is retainably placed within a container having one or more lift paddles secured within its inner cavity. The container is supported for rotation about an axis and has drive means for slowly rotating the container. As the container rotates, the lift paddles lift a portion of the retained slurry, allowing the liquid portion to fall back into the primary slurry pool to be separated, and lifting the solids toward the top of the rotation path of the paddles. The separated solids slide by gravity off of the lift paddles as they approach the top of their rotation paths and into a collection hopper and transport means that carry them away from the container. The liquids returned to the primary retained slurry within the container assist in washing the slurry for facilitating solids separation without required increase in the retained slurry volume. Continuous flow-through an multiple chamber separation containers are disclosed.

[ What is claimed is:] [24.] A slurry separator, comprising:(a) a container generally symmetrical about an axis extending through at least one end of said container, said container having a solid wall defining an inner cavity and an access port to said inner cavity formed through said one end;(b) a plurality of lift paddles mounted to said container and longitudinally extending in the axial direction across said inner cavity;(c) a support connected with said container for supporting said container for rotation about said axis;(d) an inlet extending through said access port for introducing a volume of liquid/solid slurry into said inner cavity for retention by said container;(e) an outlet extending from from said inner cavity and through said access port external of said container for collecting and carrying separated solids from said container; and(f) a drive connected with said container for rotating said container and lift paddles about said axis; wherein said lift paddles lift a portion of said slurry volume in said container and drop solids from the lifted slurry into said outlet and allow liquids from said lifted slurry to return to said slurry volume in the container.
