A trap for foreign objects, such as tramp metal, introduced into a hammer mill or the like having impact hammers supported within a mill cavity for rotational movement about a generally horizontal axis. The trap is characterized as being supported exteriorally of the mill cavity on a mill cavity access door and as being arranged in communication with the mill cavity through an access door defined opening disposed adjacent an inlet opening of the cavity. The trap is formed with a receiving chamber, a smoothly curved top wall plate extending from an upper edge of the trap opening for directing objects propelled therethrough by the impact hammers downwardly into the receiving chamber, a retaining plate extending from a lower edge of the trap opening in overlying relation to the receiving chamber for retaining objects collected therein, and a door bounding the receiving chamber for affording access to the collected objects.
