The invention describes a housing which aerates stone dust with ambient air or stone dust in an aqueous solution with concentrated CO2, the stone dust having a defined degree of humidity in order to absorb CO2. So that the stone dust does not escape from inside the housing, a plate system with a filter ensures that the stone dust is fixed in a certain position in the container.
So that the stone dust, which is moistened with the help of water mist in the supply air, does not clump and can be aerated more efficiently, the plates are partially in a state of vibration, which is generated by a frequency-controlled vibrating mechanism.
To empty the housing, the arrangement is pivoted through 180° and opened.
Preferred stones for the aeration material are granite, gneiss, gabbro and basalt rocks. Under certain circumstances, metallic parts are removed with a magnet so that the stone dust material can be used as fertilizer.
