FIELD: process engineering. ^ SUBSTANCE: proposed method uses, at least, two powder specimen holders with through channel having first opening for powder to be introduced therein and second opening for powder to be discharged therefrom. Powder specimen are fed into appropriate holders to align holder second opening with appropriate opening of specimen receiver. Note here that powder flows simultaneously through second openings in mixing powders to facilitate their flow from channels into appropriate receivers. Additionally, proposed method comprises pulling elastic film on every hole and locking it relative to appropriate holder to seal its second hole as well as film perforation to seal every second opening during powder flow through second openings. ^ EFFECT: higher accuracy of dispensing. ^ 22 cl, 7 dwg |
