Abstract

See full text

An apparatus for producing a bloated mineral granulate with a heated processing channel (1) for the mineral granulate fed to a conveying flow (13), wherein an inflow opening (4) is provided in the processing channel (1) for forming a granulate-free laminar flow (5) running along the inner wall of the processing channel, is described. In order to design a device of the type described above in such a way that a continuous, qualitatively controllable production process is achieved, it is proposed in that the processing channel (1) comprises two channel sections (16), (17) with differing cross-sections, wherein the channel section (16) with a smaller cross-section projects into the channel section (17) with a larger cross-section, forming the inflow opening (4), and wherein the channel section (16) with a smaller cross-section is enclosed by the channel section (17) with a larger cross-section in such a way that an inflow opening (4) is formed completely around the projecting region of the channel section (16) with a smaller cross-section.
