A knife for attachment to auger flighting for a bulk mixer is provided. The knife comprises an exterior cutting side, a leading end defined as the front end during rotation of the auger, a trailing end opposite the leading end. The knife includes an inboard side adapted for attachment to the auger flighting. The exterior cutting side comprises a blade edge therealong for engaging material to be cut; an angled section along a portion of the blade edge, angled upward from horizontal (angled upward from the longitudinal plane of the knife) by X°. A base knife for attachment directly or indirectly to a bottom flight of an auger flighting in also provided.

The invention relates to a capsule (3) for producing a composition, particularly for dental care, comprising an enclosure (6) provided with at least two compartments (8), the number of compartments corresponding to the number of components to be mixed, and at least one wall (10) for isolating the components, said wall (10) being provided to isolate the components form each other in storage mode, and to allow fluidic communication between the compartments (8) in mixing mode, said capsule also comprising a driving rod (2), one end of which is designed in compliance with the ISO 1797 standard, for removable attachment to a hand-held part (1).

A reactor assembly is provided for heating plastic material. The reactor assembly includes: a reactor vessel including a central axis; and an agitator mounted within the reactor vessel. The agitator includes: one or more blade(s) distal from the central axis for mixing contents of the reactor vessel in use; and one or more wearing parts mounted to the blade(s) to extend from the blade(s).
