Abstract
Method and apparatus for making a sharp separation of solids into components which are finer than the screen mesh and coarser then the screen mesh. The solids ladened fluid is introduced onto a screen to separate coarse solids from fine solids. A tray containing a body of aqueous liquid is vibrated causing the aqueous liquid to repeatedly contact the solids while on the screen to provide the needed mobility for fine particles to pass through the screen with the liquid. The aqueous liquid returns to the tray and the vibration of the tray aids in removal of the fine solids which have passed through the screen from the tray. Aqueous liquid is continuously added to the tray or sprayed above the screen to keep accumulated solids from increasing the viscosity of the aqueous liquid in the tray.
