Apparatus to reduce metal pieces into fragments

Abstract

An apparatus (10) to reduce metal pieces into fragments, comprising a supporting and containing structure (11) of: a feeding assembly (12) of metal pieces (P) to be reduced into fragments; a supporting plane (13) adapted to receive the metal pieces (P) fed by the feeding assembly (12) and developing longitudinally between a first end (13a) and a second end (13b) opposite to each other; a pusher assembly (14) disposed in proximity of the first end (13a) and adapted to exert on the metal pieces (P) fed and lying thereon a thrust towards the second end (13b) along a thrust direction (A-A) extending between the first end (13a) and the second end (13b); a drum (15) rotatably supported around its longitudinal axis (B-B) in proximity of the second end (13b) and provided with a plurality of teeth (16) which are arranged on its outer side surface (151) and which are adapted to remove fragments from the metal pieces (P) pushed against it by the pusher assembly (14) via chip removal, wherein the drum (15) is rotationally drivable around its longitudinal axis by a motor element (17); a presser assembly (18) disposed above the supporting plane (13) in proximity of the second end (13b) thereof and adapted to exert on the metal pieces (P) pushed by the pusher assembly (14) a pressure force with a component incident and directed towards the supporting plane (13); a collector assembly (19) of the fragments disposed below the drum (15).
