ABSTRACT:
In the method of the present invention, the slurry as it flows from a source thereof is pre-rotated prior to entering a circular vertical confined space that has a cut water discharge in the upper portion thereof. The pre-rotating slurry upon entering the confined space is subjected to the rotary action of first and second laterally spaced circular surfaces that have a number of laterally spaced ring-shaped surfaces situated therebetween. The circular surfaces and ring-shaped surfaces are power driven and rotate concurrently as a unit. As such rotation takes place, the boundary layers of slurry that adhere to the circular surfaces and ring-shaped surfaces are sheared from the balance of the slurry, and the slurry in the confined space rotating as a result thereof. As a result of this rotation, the slurry in the confined space sequentially discharges through the cut water to be replaced by pre-rotating slurry that enters the confined space. Tapered outer edge surfaces on the rotating surfaces direct slurry inwardly to the ring-shaped surfaces to prevent a build-up of solids in the confined space that would jam the rotation of the circular and ring-shaped surfaces. The inner peripheries of the ring-shaped surfaces define knife edges that sever particles in said slurry too large to move outwardly through the spaces between the ring-shaped surfaces into portions that can pass through such spaces.
