Abstract
A cleaner for treating a liquid suspension of mixed relatively heavy and light particles to separate such particles from each other comprises parallel top and bottom plates, an outer wall, and an interior spiral wall cooperating with the outer wall to define a spiral passage having a plurality of turns and leading to an outlet port for heavy particles in the bottom plate. An inlet port delivers the suspension to the outer end of the spiral passage, and there is a second outlet port through one of the top and bottom plates for that portion of the suspension which includes the relatively light particles. Different arrangements of outlet ports are shown to provide for use of the cleaner for forward, reverse, through flow and three-way cleaning action.
