A media mill having a cylindrical vessel which is vertically oriented and a motor-driven rotor extending through the vessel to agitate grinding media and a liquid product within the vessel. A tubular outlet housing extends radially outward from the vessel and forms an opening through which a screen assembly is removably mounted. The screen assembly comprises a stack of adjacently positioned annular rings which are supported on a tubular carrier element. Adjacent screen elements retain the grinding media within the vessel while openings between the elements permit the milled product to flow therethrough and into an interior cavity terminating in an outlet. The screen assembly extends into the interior of the vessel and is removably secured to the outlet housing by a quick disconnect retainer means.

A milling apparatus comprising: a vessel for receiving grinding media and a liquid having small particles therein which are to be milled or reduced in size within the vessel; a motor driven rotor in said vessel for agitating the grinding media; a liquid inlet through which said liquid is introduced as the grinding media is agitated by the rotor; a tubular liquid outlet housing extending radially outward from a passage through said vessel and terminating in an open end; a plurality of ring-shaped screen elements arranged in a stack within said vessel; a tubular carrier element extending through said outlet housing, said carrier element defining an interior channel and extending through said stack to support said screen elements so that all of the screen elements can be removed together upon the removal of said carrier, said carrier having one or more windows allowing fluid communication between said vessel and said interior channel, said screen elements surrounding said windows and having slots formed in their axial faces so that the slots and the adjacent screen elements define openings extending between said vessel and said interior channel, said openings being sized to prevent the grinding media from passing into the openings as said liquid flows radially inward through said stack and windows and into said interior channel; an outlet formed by an end of said carrier which is open and terminates outside of said vessel, liquid exiting the vessel through said outlet; and means for removably fastening said carrier element to said outlet housing so that said carrier and screen elements can be quickly and easily removed.
