PURPOSE:To enable enormous volume of granular powder to be precisely measured and supplied by arranging plural pairs of scratching tools each comprising a rough scratching member and a fine scratching member on a rotary table into plural stages, and gradually increasing scratching width as said stages are advanced. CONSTITUTION:A pair of rough scratching members 3-3'' and a pair of fine scratching members 4-4'' are arranged on the upper surface of a rotary table 2 below a granular powder supplying hopper 1, and granular powder supplying ports 5-5'' arranged corresponding to said members along the peripheral edge of the rotary table 2. And, the respective rough scratching members 3-3'' are arranged on the upper stream side in the powder flowing direction on the upper surface of the rotary table 2 for the respective fine scratching members 4-4'', and scratching widths a, b-a', b' of the respective pairs of scratching members 3, 4-3'', 4'' are increased as they advance to their later stages. Hereby, it is possible to precisely measure enormous volume of the granular powder and supply it at a stroke while avoiding complicated processing for excessive granular powder. |
