Abstract
Improved cleanability and contamination prevention are provided in a wet milling apparatus for the production of pharmaceutical grade milled products. The advantages are provided by a milling agitator that is characterized by a smooth, seamless agitating surface, without crevices or seams which might accumulate contamination and which might prevent removal of contamination during cleaning. The use of polymeric milling media reduces wear on the agitator and permits the agitator to be constructed with permanent, smooth welded joints. Seamless joints are also provided on the interior of the milling chamber and sanitary, threadless fasteners are provided for the media separation screen and other milling chamber fittings.
