SYSTEM AND METHOD OF MANUFACTURING MONO-SIZED-DISBURSED SPHERICAL PARTICLES

摘要

A method and apparatus (30), FIG. 1, for forming mono-sized-dispersed spherical particles from a conductive liquid (38) utilizes inductive coupling to cause a pressure oscillation in a plenum (39) feeding a jet-forming nozzle (40). The inductive coupling is provided by a transformer (34) where one loop (48) is the conductive liquid (38). The invention also features a device with single or multiple orifice nozzle plates (500) reliably manufactured using etching techniques. The invention also features methods for protecting jet-forming orifices (504) from destruction attack by a corrosive liquid. The invention also features means to create simultaneously, tailored mixtures of mono-size-dispersed powder sizes. The invention also features a system and method for "pre-wetting" fine pores and orifices and for encouraging liquid penetration of the fine pores and filter without recourse to very high differential pressure.
