(57) The invention realises a milling drum (1; 100; 200) for scarifier machines which
comprises a plurality of annular elements (4, 5) coaxially arranged outside a core
(2) connected with the driving shaft of the scarifier machine, supplied with operating
protruding elements (6) arranged like a spiral and suitable for shuttering the soil
to remove. Said annular elements comprise at least two ending annular elements (3)
realised one - piece and one or more intermediate annular elements (4, 5) in between
said ending annular elements (3), where at least one (4) of said one or more intermediate
annular elements is formed of at least two shells (41) supplied at the ends with radial
flanges (411) opposable among them which are united by fastening means (412) in order
to render these annular elements (4, 5, 3) integral among them and with said core
(2).
