ABSTRACT:
An apparatus for crushing materials such as cans into flat plate-like forms. The crushing apparatus comprises a hopper for receiving material-to-be-crushed, a feeder, and a symmetrical array of vertically stacked pairs of parallelly aligned, opposed counter-rotating rollers. The feeder includes a rotating element having an axis of rotation parallel to the rotational axes of the rollers, and further having two opposed elongated feed members, each being disposed with a corresponding longitudinal axis substantially parallel to and displaced a predetermined distance from the rotating element axis of rotation. The rotating element is pivotally mounted on a pair of spring loaded lever arms in a manner permitting displacement of its rotational axis between predetermined limits along a cylindrical surface of rotation having an axis of revolution parallel to the roller axes. The feeder is positioned relative to the roller array such that the feeder rotating element axis of rotation is offset from the plane of symmetry between the opposed rollers. The rollers forming one side of the array are mounted on a pair of spring loaded lever arms which force the lowermost pair of rollers into contact to form a downwardly converging array when no material-to-be-crushed is between the lowermost rollers, and which allow the array to expand otherwise. A driving means rotates the rollers and feeder rotating element so that material-to-be-crushed introduced to the feeder is passed downwardly through the array.
