Means and a method for feeding doses of fluidisable materials, comprising a supply of material (1, 2, 2') and a discharging air slide (3) with at least one fluidisable element (5) in its bottom, where said element, when activated, being able to transport material towards one outlet (8) for controlled dosage. Upstream the discharging air slide (3) there is arranged a substantially vertical distance tube (4, 4') that connects the supply of material (1, 2, 2') with the discharging air slide (3). The distance tube has a height to diameter ratio that will ensure a constant hydrostatic pressure towards the discharging air slide (3) at different filling levels. |
