ROTARY MIXED-MATERIAL FEEDER

摘要

PROBLEM TO BE SOLVED: To provide a rotary mixed-material feeder which can feed a homogeneously mixed material comprising raw materials different in specific gravity to a vibration feeder without excessively increasing the number of production steps and without needing a large-sized apparatus. SOLUTION: The rotary mixed-material feeder comprises a bottomed cylinder 11 with spiral ribs 11a and 11b formed on almost all the area of the inside surface and a lid 12 having an opening 12c and attached to the open end of the bottomed cylinder. On the inside surface of the bottomed cylinder, a straight line ribs 11f crossing the spiral ribs are formed. COPYRIGHT: (C)2004,JPO
