VOLUME DOSER Russian patent published in 1999 - IPC

FIELD: pyrotechnic production. SUBSTANCE: volume doser for loose material has dosing disc mounted on shaft for rotation and provided with measuring holes positioned over circumference, bunkers for compounds fixed above measuring holes. Measuring holes on dosing disc are located on two and more concentric circumferences. Difference between diameters of two adjacent circumferences exceeds sum of diameters of two largest measuring holes on the circumferences. Minimum space between two adjacent holes equals half the product of dosing disc diameter by sum of relations of diameters of these holes to diameters of circumferences on which they are made. Number of circumferences is equal to number of dosed compounds, and only one bunker for compound is secured above every circumference. EFFECT: higher efficiency and safety. 2 cl, 2 dwg
