The screw feeder is extensively used as a feeder of granular materials. Until now, a few reports regarding the fundamental characteristics of the screw feeder, for example, the required power and the quantity of discharge from the feeder, have been published. However there are almost no reports on the dynamic characteristics and the transportation mechanism. In this paper, the transporting state and the transportation mechanism of granular materials inside the screw feeder are investigated. First, the effects of the rotating speed of the screw shaft and the pressure of granular materials inside a feed hopper on the required power and quantity of discharge are examined. Secondly, the transporting state of granular materials inside the screw feeder is investigated. Then the transportation mechanism is discussed by analyzing the motion of a tracer inserted into the screw feeder and by using a velocity diagram.
