Abstract

942,918. Rotary drums. G. BOJNER, and G. BOJNER. July 18, 1962 [Aug. 17, 1961], No. 27646/62. Headings F4G and F4U. A rotary drum heater, drier or cooler 1 for granular &c. material has longitudinally extending lifting bars 7 angularly bent in the direction of rotation of the drum along a line coincident with the base of tongues 8 formed therein, which tongues are separated by relatively wide spaces 9. The bending angle of the tongues e.g. between 90 and 120 degrees enables them to carry the material beyond the highest point of the drum revolution before cascading the material into contact with a gaseous treating medium introduced into the drum at 17. The lifting bars 7 are secured to the inner drum surface by angle pieces 10 in the central section of the drum but in the right hand end portion of Fig. 1, they are interconnected as by end rings 11 to form a separate cage having a diameter smaller than the drum so as to roll freely therewithin. In the left hand portion the bars toward the discharge 6 are omitted and a unit for heat exchange and dust separation comprising channel shaped sectors 12 and longitudinally extending partitions 13 is utilized which may either be mounted on the shell of the drum or in a freely rolling cage. Feeding bars formed as separation sectors or sheets 15 are mounted on the bars 7 in a helical fashion and are spaced from the drum shell.
