Abstract

The invention relates to an impact breaker which includes a rotor (1) having a first wall (5) and a second wall (6), and an integral striker (2) connected to the rotor. The striker is arranged between the first wall and the second wall and projects radially beyond the first wall and the second wall. The striker has, when new, an end wall (51), a wearing portion and a supporting portion defined by a plane parallel to the end wall and tangential to one end of the second wall (6). The ratio between the volume of the supporting portion and the total volume of the striker when new is less than 0%. The striker (2) is connected to a mounting (3) connected to the rotor and suitable for being separated from the mounting without separating the mounting from the rotor. A removable shaft (10) passes in series through openings made in the striker (2) and in the mounting (3).
