PURPOSE:To provide continuous constant-quantity supply of a plurality of sorts of materials with one unit of machine by adjusting its capacity unitarily through the use of gate opening, wherein any desired mix proportion shall be obtainable. CONSTITUTION:A mix proportion adjusting hopper 2 is partitioned by separators 7 into compartments and filled with a plurality of sorts of materials, which, with rotation of a feed roll 9, are exhausted one after another to an exhaust chute via a passage 11 formed between a control gate 10 and said feed roll 9, wherein the mix proportion is determined by the position of the above- mentioned mix proportion setting separator 7. Here the amount of exhaustion can be set unitarily through adjustment of the revolving speed of the feed roll 9 and adjustment of the opening of said passage 11 to be obtained by adjusting the said control gate 10, which should provide continuous constant-quantity supply at precise mix proportion.
