METHOD AND DEVICE FOR MANUFACTURING SPHERICAL PARTICLES OUT OF LIQUID PHASE

摘要

To manufacture spherical particles out of liquid phase with a narrow grain spectrum using melting temperatures of up to 1500.degree.C by generating droplets by means of vibrating nozzles, the liquid phase, the nozzle and the drop distance for the droplets are maintained at a constant temperature of 1 to 10.degree.C above the melting temperature of the liquid phase until the spherical shape of the falling droplets has stabilized. The particles must then be abruptly chilled.
