FIELD: apparatuses for powder surfacing and soldering-on two-component mixtures of different fraction size in vacuum. ^ SUBSTANCE: powder feeder includes hopper and metering unit having mixer with opening in its base for feeding powder. Hopper includes coaxial outer and inner containers with bases in the form of cones mounted with possibility of vertical motion of inner container relative to outer one. Hopper is joined through sleeve with damper provided with metering unit having motor and driving roller. Mixer is mounted with possibility of rotation and it is inclined by angle 45 - 60° relative to horizontal plane. ^ EFFECT: possibility for providing uniform two-component powder mixture of different fraction size. ^ 4 dwg |
