Blade holding disc for mixer rotor has several removable blades comprising metallic plates bent along transverse fold line to define two parts, one having two fixing holes

摘要

Several removable blades (LG,LD) are mounted in the disc periphery. The blades comprise metallic plates which are bent along a transverse fold line (7) to define two parts (5,6) having an angle between them. One of the parts fixed to the disc (1) comprises two disc fixing holes (8,9). The distance between the centers (10) of the two holes is parallel to the fold line and located at a distance of between 15 and 50 mm from the fold line. The edge (D1,D2) of the disk which is perpendicular to each blade is parallel to the fold line of the blades and located at a short distance from it.
