Abstract: A compression device for a scrap-shredding plant, comprising at least a rotating roller element able to cooperate with a feed surface for feeding of scrap to the plant in order to grip and compress the scrap between the roller element and the feed surface. The roller element comprises a hollow tubular structure able to be dis-assembled, having semi-cylindrical cap elements reciprocally coupled during use with a rotation shaft of the rollers.

Abstract: A contrasting device for a shredding plant comprising shredding members for shredding. The contrasting device comprises one or more contrast portions assembled in an independent and removable manner onto a frame of the plant, and assembly elements cooperating with each contrast portion, so as to determine the independent and removable assembly onto the frame. Each contrast portion comprises a symmetrical contrast profile with respect to a contrast edge. The profile is defined by a first segment and by a second segment substantially equal to each other.

Abstract: A cover device for a shredding plant, able to cover at least a shredder unit comprising a rotary drum able to rotate around its own axis of rotation inside a shredding chamber. The cover device is provided with a plurality of separation means to separate and discharge the materials arriving from shredding.

Abstract: A shredding device comprising a drum having a central hub rotating around an axis on which a plurality of discoid elements are mounted adjacent, able to rotate solidly together and carrying peripherally beating elements. Each discoid element comprises a set of beating elements which comprises at least a pair of beating elements and, along the axis, the pairs of beating elements of the discoid elements are disposed angularly staggered with respect to the same axis.
