A powder feeding assembly for feeding a flame-melting device is disclosed. The powder feeding assembly includes a powder holding chamber with a screening member and a brush assembly disposed therein. The brush assembly includes at least one bristle element having a distal and a proximal end. The distal end is disposed proximate to the screening member. Powder held in the powder holding chamber is urged through one or more openings in the screening member by rotating the brush assembly. The powder is then delivered to an input section of the flame-melting device for processing.
