Abstract:
In a fragmenting machine equipped with power feeding means for horizontally feeding feed materials onto a radial pathway of shearing teeth carried upon a rotating cylinder housed within a fragmenting zone and a screen for screening fragmented feed materials to a desired particle size, the improvement which comprises an adjustable feeding and striking ramp assembly for supporting an angular disposition of the feed material ramped onto the radial pathway of the shearing teeth, with said adjustable feeding and ramping assembly comprising a feeding and striking section pivotally mounted at a feed inlet end so as to permit an adjustable radially positioning of the feed materials upon the feeding and striking section for shearing by the shearing teeth as the feed materials are power fed onto the radial pathway of the shearing teeth and a detent spacer for elevating and maintaining the feeding and striking section at a desired radial positioning for feeding feed materials onto the radial pathway of the shearing teeth.
