ABSTRACT:
A particulate material feeder includes a hopper sectioned into two receptacles for accommodating two different kinds of particulate materials. Each particulate material falling down through a bottom opening of the receptacle is introduced into a feed channel defined between a feed roller having a frictional periphery and a control gate having a semi-circular cross-section. Thus, a pair of feeding systems for two different kinds of the particulate materials are symmetrically provided within a single apparatus. An opening degree of the feed channel may be controlled separately and independently in each feeding system so that a definite mixing rate of the two kinds of particulate material can be obtained as desired. On the contrary, the feed rollers provided in the two feed systems are driven by a single driving source and are thus rotated at the same speed. This rotational speed determines a feed rate of the particulate materials which, with the present device, are premixed at a given mixing rate and obtained in a common region disposed beneath the feed rollers. One of the receptacles may further be divided into sub-sections to accommodate an additional kind of particulate material such as additive.
