Method and apparatus for producing metal particles and, in particular, spherical stainless-steel shot for shot blasting

摘要

An apparatus according to the invention uses a caisson 10 whose curved front wall 30 uses the Coanda effect in order to suck an induced gas stream I from the environment towards a primary gas stream Pr which emerges via a slot 70 in the caisson and follows the outer surface C of the front wall 30 of the caisson. Molten metal from a reservoir 90 is introduced between the two gas currents and the interaction produced divides the metal current into particles P having the desired size, shape and composition. <IMAGE>
