ABSTRACT:
The invention relates generally to a screen used for separating lubricants from solid materials, and more particularly, to a centrifugal parts separator having a screen which assists in separating lubricants from metal or other scrap materials. The screen of the present invention preferably comprises a cylindrical shaped member which can be formed in one or more component parts with a plurality of spaced fluid passage openings therein. The screen is made so that the ratio of the distance between the openings to the median width of the openings is at least 18/1, thereby providing increased surface wear area of the screen.
