ABSTRACT:
A screen for use in a separator device includes an inner portion opening onto the screen inner surface and an outer portion extending the remainder of the way through the screen material. The outer portion of the screen opening allows the desired material to pass therethrough, while blocking the entry of large pieces of hard material. The inner portion of the screen opening includes a deflecting surface forming an acute deflecting angle with the inner screen surface in the direction at which a cutting element passes over the screen opening. Large pieces of hard material that may partially enter the screen opening are pressed against the deflecting surface as the cutting element passes over the screen opening, the deflecting surface serving to deflect the hard material out of the screen opening without chipping off or cutting off any of the hard material, which could then pass through the screen opening along with the desired material.
