<p>The invention relates to a feeding and mixing arm 2 for a drum composter, which arm is attached to a revolving shaft 4 which passes through the casing 1 of the drum. The rotor plates 3, 5 are attached to the shaft 4 in such a position in relation to each other that the section made transversely to the plates 3, 5 has the form of the letter Y. When the arm 2 is in the feeding position, the direction of the plate 5 forming the foot of the Y departs, by a desired feeding angle, from the perpendicular plane with respect to the shaft of the drum. <IMAGE></p> |
