What is a scalper? Is there a difference between a screen and a scalper?
1 answer
Un écran, souvent appelé crible (ou tamis), est un dispositif similaire, mais il est généralement utilisé dans des étapes du processus qui nécessitent une séparation plus fine des matériaux selon différentes tailles de particules. Les cribles peuvent être vibrants, rotatifs ou statiques, et sont disponibles dans divers designs adaptés à des applications spécifiques.
La différence réside principalement dans leur application et leur finesse de séparation : un scalper est conçu pour éliminer les matériaux grossiers en amont, tandis qu'un crible effectue une séparation plus détaillée et en aval. Dans certaines configurations, un scalper peut précéder un écran pour optimiser l'efficacité du processus global de triage ou de broyage.
