Abstract

Molino para moler material en polvo y método correspondiente. El molino tiene una cámara de separación cilíndrica dentro de la cual se introduce material en polvo como dispersión en un chorro de gas. Material en polvo es suministrado inicialmente a través de dos entradas de polvo espaciadas situadas cada una entre un surtido y un conjunto de cuello de tubo venturi, de modo que el fluido de molienda introduce el material en polvo a través de los tubos venturi, y éstos están montados en oposición de modo que los chorros de gas portadores del polvo se golpean entre sí para impartir la molienda. El material golpeado pasa a un tercer tubo venturi para ser arrastrado en un gas procedente de una tercer boquilla surtidora e introducido a través del tubo venturi al interior de la cámara de separación. El molino es de particular uso para moler polvos pigmentarios.
