Device for kneading a paste allowing a paste to be kneaded and extruded reliably and in a stabilized manner notably for the manufacture of explosives, and offering greater ease of maintenance. According to the invention, this paste-kneading device comprises an oblong barrel (10), two shafts (14a, 14b) running parallel to one another within the barrel (10), held and driven at their first ends (15a, 15b) defining the upstream end (AM) by a drive device (12), two screws (20a, 20b) each formed of flights borne by the shafts (14a, 14b), each screw (20a, 20b) comprising at least one transport section (21a-21d) bearing a main flight (21') for progressing the paste along the two screws (20a, 20b), and an outlet orifice (19) made in the wall of the barrel (10) to discharge the kneaded paste; the kneading device further comprises a retaining device (30) configured to hold each shaft (14a, 14b) at its second end (16a, 16b), defining the downstream end (AV), and allowing it to rotate freely, this retaining device (30) comprising, for each shaft (14a, 14b), a first part (31) secured to said shaft (14a, 14b) and a second part (36) secured to an end cap part (13) of the barrel (10), this end cap part (13) being removable and said first (31) and second (36) parts being configured to engage and disengage freely. |
