1. A method for recovering two or more product streams from a feedstock, the method comprising:
receiving the feedstock comprising a principal component and at least one secondary component, wherein a friability of the principal component is different than the friability of the at least one secondary component, the feedstock falling in a direction of gravity into a rotary impact separator;
passing the feedstock through the rotary impact separator comprising a body with one or more walls that define a chamber, an impact device that extends through the chamber, and a screen covering an outlet in the body below the impact device relative to the direction of gravity;
rotating the impact device within the chamber and contacting the feedstock with the impact device; and
collecting a principal component stream with reduced levels of the at least one secondary component by passing the principal component stream through the screen and the outlet, wherein an axis that extends perpendicular to a shaft of the impact device intersects the wall and not the screen above the impact device relative to the direction of gravity, and the same axis intersects the screen and the outlet and not the wall below the impact device relative to the direction of gravity.
