MACHINE FOR SIEVING OF DIFFICULT-TO-FLOW POWDERS

摘要

FIELD: equipment for sieving of oxidizer for blended solid rocket fuel. ^ SUBSTANCE: machine has box with shell and sieve, drive with eccentric shaft and rubbing activator with spokes. Rubbing activator is loosely arranged on sieve with radial gap relative to shell. Spoke ends are equipped with springy compression members, whose length is determined from mathematical expression. Radial gap between activator spoke ends and box shell is 0.5-1.0 the eccentricity of shaft. ^ EFFECT: increased efficiency in sieving of powdered materials. ^ 6 dwg
