Abstract

resumo método e dispositivo para produção de granalhas um método e um dispositivo para a produção de granalhas são providos, em que a produção é melhorada. em um espaço (5) para a formação de gotas fundidas, cujo espaço é circundado por água (1) em um tanque (20), por uma cobertura (3) para cobertura de uma área circundando um disco (2) que está localizado acima da água e roda, e por uma panela intermediária (4) que penetra através da cobertura, um gás é descarregado através de uma abertura (6) que é formado na cobertura e o filme (9) de água é formado na superfície interna da cobertura. o metal fundido (10) flui através do orifício (11) no fundo da panela intermediária para ser suprido para o disco rotativo. as gotas fundidas são formadas por uma força centrífuga a partir do metal fundido que foi suprido para o disco. então, as gotas fundidas são feitas colidirem com o filme da água na superfície interna da cobertura, para serem divididas em gotículas que são menores do que as gotas fundidas. as gotículas são resfriadas e solidificadas.
