Abstract (en)
[origin: EP0367956A1] In the treatment of a granular substance, which is capable of being at least partly scattered, in a cooling drum, satellite cooler, rotary drum furnace, drum-type drier or similar devices, in order to increase the thermal efficiency, such as, for example, the cooling effect, in the critical heating zone without having to tolerate a perceptible increase in the dust load of the gas flow as well as an increase in the dimensions of the rotary drum, rotary drum lifters are proposed according to the invention, which rotary drum lifters, as viewed in the drum cross-section, consist of roughly hemispherical curved elements (13) which project arch-like into the drum interior and, in their apex region at their two front edges, each have a rim (19, 20) directed towards the inner wall of the drum, reducing the free curved cross-sectional area and preventing the scattering of the lifted substance located in the curved elements. <IMAGE>
