Abstract (en)
[origin: ES284574U] Mixing silo for pneumatically homogenizing fine-grained or dust-like material, the bottom of which comprises groups of aeration zones which can be alternately supplied with compressed air in such a manner that in each group a bottom zone partially limited by the outer limit of the silo bottom is heavily aerated and a bottom zone located between the heavily aerated bottom zones is aerated only weakly. An even, progressive circulation of the entire silo contents with little expenditure of energy is achieved by separating the heavily aeratable bottom zones from each other with a star-shaped, exclusively weakly aeratable bottom zone and by constructing the outlet as an overflow.
