Abstract

L'invention concerne des équipements de broyage de matériaux et peut s'utiliser dans des industries de construction, chimique, de peintures et vernis, alimentaire ou autres. L'invention permet d'augmenter la productivité du processus de broyage de matériaux solides et d'améliorer la qualité du produit fini. Le procédé de broyage de matériaux comprend l'acheminement d'un matériau de base dans un flux de gaz et/ou de liquide dans un espace entre deux rotors tournant rapidement qui sont alimentés par une tension élevée modulée en amplitude et/ou en fréquence ainsi qu'une haute tension pulsée.
