  • said cutting section can comprise two couples of paired rolls arranged one after the other, the rolls of each couple being suitable to receive between them said materials in order to chop them.
  • each roll of said inserting-crushing section comprises longitudinal tabs tilted according to the rotation direction.
  • each couple of cutting rolls comprises a first roll provided with helicoidal grooves, realising cutting edges, and a second roll, paired to the respective first roll, made by a resilient deformable material, like iron-lead alloy (AVP).
  • AVP iron-lead alloy
  • said cutting edge has the couples of rolls arranged in such way that said first and said second rolls of each couple are in opposite position with respect to the rolls of the following couple.
  • said first rolls of each couple of rolls of said cutting section has different groove pitches.
  • said apparatus can comprise according electrical moving means, as a motor, of said rolls of said inserting-crushing section and of said cutting section.
  • said apparatus can comprise a mechanism having gear wheels, fixed to the rotating axes of said rolls, motion transmission means, as belts and/or chains, coupled to said gear wheels, and at least one reduction gear, which overall arrangement is such that it rotates the rolls of said inserting-crushing section and of said cutting section.
  • each roll can rotate according to a direction opposite to the rotation direction of the relevant opposed roll.
  • said apparatus can comprise a hopper in correspondence of said at least one introduction-crushing section, suitable to receive said material introduced within said mouth.
  • said apparatus can comprise a lid for closure and opening of said mouth, connected with a safety device, such as an electric switch, so as to prevent operation of said apparatus when in the opening position.

  • apparatus 1 for grinding comprising a introduction/crushing section 2 provided with a first couple of rolls 21 and 22, opposed each other, each roll comprising longitudinal tabs 3 on its surface, having a triangular cross-section and slanting according to the rotation direction of said rolls 21 and 22.
  • Rolls 21 and 22 rotating according to opposite directions, as indicated by arrow A in he figures, can drag, crush and fold event bulk objects (bottles, tanks, packagings) so as to reduce total energetic absorption.
  • said rolls 21 and 22 are comprised of steel F37, while crushing tabs are comprised of Steel C40, with induction hardening of ridge.
  • Axis distance between rolls 21 and 22 is of 90 mm, while centre of crushing blade is offset, with respect to the rotation axis, of 10 mm. Diameter of each roll measures 60 mm, while the total diameter is 105 mm. This positioning permits to have a larger distance between rolls at the entrance and to receive materials larger than the axis distance, measuring 128 mm.
  • insertion-crushing section 2 reduces thickness of an inserted material from original dimension up to a suitable measure for proper subsequent chopping. Measure between top of tab 3 and opposed roll surface has been calculated in the preferred embodiment to be 8 mm.
  • a chopping section 4 is provided, providing in sequence a first pair of rolls 41 and 42 and a second pair of rolls 43 and 44.
  • Each one of said roll pairs comprises a first chopping roll, respectively rolls 441 and 43, comprised of K110 steel, hardening under vacuum, each one presenting helicoidal grooves 5, possibly with different pitches between first chopping rolls 41 and on surface, realising chopping profiles, obviously helicoidal as well, and a second buckling roll, respectively 42 and 44, comprised of resiliently deformable material, such as lead or AVP, the function of which will be better described in the following.
  • pair of rolls 41, 42 and 43, 44 have such an arrangement that said first and second rolls of each pair is crossed with respect to the following pair. This permits obtaining a much more chopped material.
  • Chopping rolls 41 and 43 have been studied to reduce contact surface between chopping profiles and surface of material to be chopped... thus, helix is inclined so that contact surface has a minimum value, in order to have maximum chopping yield, by choosing a suitable angle of helicoidal grooves 5 helix.
  • Angle of said helicoidal grooves 5 can be any angle, but preferably included between 45° and 35°. In the present case, the angle is 37°.
  • Rolls 21, 22, 41, 42 and 43, 44 have, each one, a single rotation axis, fixed on a fix structure 6.
  • Apparatus 1 also comprises a mechanism 7 with toothed wheels 8 coupled on rotation axis of said rolls 21, 22, 41, 42, 43 and 44, and placed in such a way that each roll rotates according to an opposite direction with respect to the relevant opposed roll. Rotation direction of each pair of rolls is shown in the figures by arrows indicated by letters A, B and C.
  • An electric motor (not shown in the figures) is mechanically coupled with said mechanism 7 so as to operate the same rotating rolls of the above insertion-crushing 2 and chopping 4 sections in a suitable way, as described in the above.
