Adjustable feeding and striking ramp

A method for adjusting a radial positioning of feed materials power fed onto a radial pathway of shearing teeth rotating about a fixed axis of a rotor in a fragmenting zone of a fragmenting machine equipped to horizontally feed materials to an adjustably feeding and striking ramp assembly equipped to adjustably position the feed materials thereupon at a predetermined radial positioning for shearing by the shearing teeth as the feed materials are power feed to the fragmenting zone for fragmenting into fragmented pieces, by said method comprising:

• a) ascertaining fragmenting characteristics of the feed materials to be power fed to the fragmenting zone;
• b) adjusting the adjustable feeding and striking ramp assembly to the predetermined radial feed positioning for intercept onto the radial pathway of the shearing teeth so as to accommodate for the fragmenting characteristics of the feed materials and
• c) power feeding the feed materials to the fragmenting zone while maintaining the adjustable feeding and striking ramp assembly at the predetermined radial feed positioning for the shearing thereupon by the shearing teeth.

A method for altering the fragmentation of feed materials power fed onto a radial pathway of shearing teeth rotationally carried upon a rotating cylinder in a fragmenting zone while supporting the feed materials upon an adjustable feeding and striking ramp which serves to supportively and radially position the feed materials for striking by the shearing teeth and allows for an alteration of a radial feed positioning of the feed materials thereby supportively power fed onto the radial pathway of the shearing teeth, said method comprising:

• a) adjusting the adjustable feeding and striking ramp to a desired radial feed positioning for the feed materials being power fed to the fragmenting zone;
• and
• b) fragmenting the feed materials power fed to the fragmenting zone while maintaining the feed materials at the desired radial feed positioning.

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, a releasable cradle assembly supportively carrying a removable 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 materials 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 serving as a supportive anvil for the feed materials fed onto the radial pathway of the shearing teeth and a detent spacer securely anchored to the cradle assembly 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, which releasable cradle assembly upon subjecting to an excessive shearing force releases the cradle assembly and the securely anchored detent spacer from a fragmenting position.
