FIELD: process engineering.SUBSTANCE: invention relates to adjustable separators that allow adjustment of material particles sizes at mill for solid propellant and can be used for separation of coarse particles from minor particles caught by upward airflows. Separation system comprises casing of, in fact, round cross-section, internal chamber constricted by truncated cone arranged inside said casing, external chamber arranged between casing and cone, sorting ring fitted at cone top part with multiple openings with blades and fuel duct outlet above said sorting ring. Said blades are articulated with every opening to open and close it.EFFECT: optimised grinding.14 cl, 4 dwg |
