In a device for batching powder materials, an Archimedean screw batching member is arranged inside a batching channel, coaxial with the batching channel and operated to rotate by a relative actuator, to convey batched quantities of a powder material to an outlet section of the batching channel. An additional Archimedean screw batching member is arranged inside a feeding channel and id coaxial with the feeding channel. The feeding channel is set in communication with the batching channel. The additional Archimedean screw batching member is operated to rotate, by a relative actuator, to feed the powder material to the batching member.
