Liquid metal fragments

Droplet Formation in Water Atomization. In water atomization of melts, liquid metal stream may be shattered by impact of water droplets, rather than by shear mechanism. When water droplets at high velocities strike the liquid metal stream, some liquid metal fragments are knocked out by the exploding steam packets originated from the water droplets and subsequently contract into spheroidal droplets under the effect of surface tension if spheroidization time is less than solidification time. It is assumed that each water droplet may be able to knock out one or more metal droplet. However, the actual number of metal droplets produced by each water droplet may vary, depending on operation conditions, material properties, and atomizer designs. 

Note. (1) In general the apparatus used in these metal-liquid ammonia reductions is essentially that shown in Fig. 2.69 (d), but without the dropping funnel tube extension. The dropping funnel is replaced with the soda-lime guard-tube, which may then be removed at appropriate intervals for the periodic addition of metal fragments. After the flask has been charged with liquid ammonia, the inlet tube is replaced with a suitable thermometer, the bulb of which should be immersed in the reaction solution. A dry ice-acetone cooling bath should be used. 

The main waste materials from destroying chemical munitions are solids soot, charcoal, gravel, inorganic dust, and metal fragments from the weapons. The only liquid waste from the DBG is spent hypochlorite solution from decontamination of the system prior to maintenance operations. ...
