Abstract
Disclosed is a horizontal media mill comprising a cantilevered shaft extending from a motor into a vessel in which rotor discs mounted on the shaft agitate the grinding media and the product being milled. A cup-shaped screen and a cup-shaped end cover fit over the free end of the rotor and are removably mounted on the end of the vessel. The screen retains the grinding media in the vessel while permitting the milled product to flow therethrough to an outlet in the end cover. The vessel is tiltable towards the screen end to facilitate cleaning and removal of the grinding media or screen elements. The stack of screen elements is radially positioned by ribs on the surrounding housing and axially clamped against lugs by an externally threaded nut. Also disclosed is a similar screen and outlet construction for a vertically oriented sand mill.
