PURPOSE:To effect fine-adjustment of a supply amount by arranging rotors of specific structure in the neighborhood of a reticulation in a vessel with the reticulation provided at the bottom and supporting the rotors, in a freely rotatably manner, on a rotary shaft along the surface of the reticulation. CONSTITUTION:A reticulation 3 is provided at the bottom of a vessel and rotors 4, 4' are arranged near the reticulation 3 of the vessel 2. These rotors 4, 4' are supported, in a freely rotatable manner, by a rotary shaft 8 along the surface of the reticulation 3. The rotors 4, 4' composed of rollers 5, 5' as a lower part and plate-like bodies 6, 6' as a lower part, are installed in a freely rotatable manner, on a rotary shaft 8 in the center of a section between the rollers 5, 5' and the plate-like bodies 6, 6'. This device is used as an appropriate one when powder is measured exactly and in a short time, and allows fine- adjustment of the supply. In addition, the lower part of the rotors is a roller, so that it does not damage or wear out the reticulation, if it comes in contact with the latter. |
