POWDER PROPORTIONER FOR PREFORMER AND METHOD OF PRODUCING NUCLEAR FUEL TABLETS Russian patent published in 2011 - IPC B22F3/03 B30B15/30 G21C21/10 

FIELD: process engineering.

SUBSTANCE: invention relates to nuclear fuel powder performers. Proposed device comprises table 2 with multiple compaction female dies 4 arranged at least in line (R1, R2), top and bottom male dies to compact powder in said female dies, powder proportioner, at least one batch funnel and drive to displace proportioner along direction X. Note here that proportioner comprises slide with its housing on top wall 16 comprising appliance for connection with at least one powder feed tube 10 and appliances (19, 23, 119) to distribute powder along axes parallel with said direction X arranged on slide housing walls (18.1, 18.2) perpendicular to said direction X that feature ramp profile in plane parallel to that of displacement. Note here that distance between female dies 2 equals that between bottom sections 25 of distribution appliance teeth while said slide is arranged on table 2 to embrace every female die 4 by every bottom section 25 between two teeth during slide displacement.

EFFECT: uniform distribution of powder, shorter cycle.
