APPARATUS FOR MAKING RED PHOSPHORUS ABSTRACT OF THE DISCLOSURE: The disclosure relates to an apparatus for making red phosphorus by subjecting molten yellow phosphorus to a thermal conversion reaction in a drum packed with ball- shaped material and provided with a first and second rotat- ably mounted shafts, of which at least one is a hollow shaft. More particularly, a rotatable feed duct (5, 6) is tightly connected to each of first hollow shaft (2) and second hollow shaft (3); a floor-anchored torque-support- ing means (7) is secured to each of the two rotatable feed ducts (5, 6); an open-ended stationary tube (8) is passed through rotatable feed duct (5) and also through the first hollow shaft (2), the tube terminating with its open end at a point where the first hollow shaft (2) opens into the drum (1); a second unilaterally closed stationary tube (12) is passed through the second rotat- able feed duct (6) and also through the said second hollow shaft (3), the tube terminating with its closed end at a point where the second hollow shaft (3) opens into the said drum (1); and a pressure-receiving means (15) is mounted in a lateral opening provided in said second rotatable feed duct (6).
