ABSTRACT:
A series of screens for use with a size reduction machine have a tapered apertured wall formed into a frusto-conial shape, with an open wide end and a narrow closed end. All screens of a particular series have a cylindrical section, the same interior depth, outside diameter and angle of the tapered wall. Despite variations in the material wall thickness, screens of the same series are interchangeable on a size reduction machine and the gap can remain constant without any adjustment to the impeller. Further, a size reduction machine has means external to the machine providing for infinite adjustments to the gap. With previous machines, each time that a screen of a different thickness was used, it was necessary to make an adjustment to the gap in order to maintain the same gap. Further, when an adjustment to the gap is required, that is accomplished by removing the screen and impeller from the machine and inserting spacers onto the shaft.
