Estimating the term…
A feeder device for feeding powder, having a barrel feeding channel with a downstream end. The feeding channel including at least one conveying element for conveying the powder material to the downstream end. A rotatable exit element provided at the downstream end of the feeding channel. The rotatable exit element includes an annular portion defining exit openings defined by powder engaging edges. The rotatable exit element is positioned transversally outside the barrel in a proximity of the downstream end of the feeding channel. The feeding channel has a first, inner diameter and the rotatable exit element has a second, outer diameter, where the second, outer diameter is equal to or larger than the first inner diameter.
A feeder device for feeding powder, comprising a feeding channel with a downstream end, said feeding channel comprising at least two conveying elements for conveying the powder material to the downstream end, and two rotatable exit elements provided at the downstream end of the feeding channel, said rotatable exit elements each comprising an annular portion defining exit openings defined by powder engaging edges, wherein the rotatable exit elements are positioned transversally outside the feeding channel in a proximity of the downstream end of the feeding channel, wherein the feeding channel comprises two merged portions each having a circular outline, each circular outline having a first, inner diameter and the rotatable exit elements each having a second, outer diameter, and wherein the respective second, outer diameter is equal to or larger than the respective first, inner diameter, and wherein a play is present between overlapping portions of the two rotatable exit elements.
