Abstract
A suspension type damper unit, a suction type powder collector and an air mixing suction type powder collector are disclosed, which have a cover plate suspended at a material discharge port thereof with a suspension member so as to form a space for the material discharge port. In these apparatus, the cover plate functions to close the material discharge port by receiving suction force by which a powdered material is fed into the material collector and opens the material discharge port by receiving the weight of the specified amount of the powdered material which is stored in the material collector.
