Inner lining for rotary drum mills (2), which lining comprises at least one metal section bar (1) suitable for being fixed to the inner surface of a rotary drum (2), wherein the upper portion of the section bar (1) is shaped for forming a head suitable for being press-fitted into a complementary groove made in an elastomeric member (3), so as to fix the latter onto the inner surface of the rotary drum (2), while the lower portion of the section bar is shaped for forming a neck narrower than the head, so that two lips (3a) arranged along the lower edges of the groove of the elastomeric member (3) are comprised between the head of the section bar (1) and the inner surface of the rotary drum (2), wherein the section bar (1) comprises a canal (1a) which is open downwards and is shaped with two opposing ribs (1b) which protrude inwards along the lower edges of the canal (1a) for retaining a fixing member (4) which can be inserted into the canal (1a) from an end of the section bar (1).
