Description:
In designing the experiments, we found it necessary to design a new technique for feeding spherical particles into the flume. The reason is that typical feeding techniques (vibratory feeders, screw feeders) are not suited to the large, smooth, spherical shape of the marbles that we used. Furthermore, we wanted a method that provided precise control of the feed rate.Our solution was to create a rotating particle catcher attached to a gear motor, as described in the equipment link.
