The efficiency of a screening operation may be evaluated by simple mass balances over screen. Consider that the feed to a screen consists of materials A and B, where A is the oversize and B is the undersize material. Out of the total materials fed to the screen, some part of it is removed as overflow and remaining part is collected as underflow.The efficiency of a screening operation may be evaluated by simple mass balances over screen.
