Conclusions
An apparatus was developed for an investigation of the vibrovacuum compaction with a liquid auxiliary load of powders prior to isostatic molding, and the efficiency of the process was determined.
The relations were determined between the compaction of the powders with vibrovacuum activation and their bulk density and angle of repose, and between the distortion of the shape of the green product and the compressibility in isostatic molding.
An efficient flow sheet was developed for the vibrovacuum compaction of products from fine-ground zircon and chromic oxide prior to their isostatic molding, viz., pouring the powder into the vibrating mold, applying the vacuum, vibrocompaction, and vibrocompaction with an auxiliary load.
Methods are recommended for producing the vacuum and vibration and for applying the liquid auxiliary load.
