ABSTRACT OF THE DISCLOSURE 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 different two 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 is obtainable as desired. On the contrary, the feed rollers provided in each feed systems are driven by a single driving source to rotate at the same speed, which determines a feed rate of the particulate materials premixed in 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 for accommodating an additional kind of particulate materials such as additives. - 13 -
