A meat grinder includes a bone chip remover in which the bone chips are removed at a radially outer region of the grinding plate through a single tangential opening substantially in the plane of rotation of the knife in response to intermittent operation of a valve. Knife blades which have substantial axial depth perpendicular to the plate are curved rearwardly to the direction of rotation, to apply an outward force component or pumping to chips which do not pass through the grinding plate, have terminal ends which sweep about a region radially outwardly of the perforated region of the plate, at a non-grinding or non-perforated region, behind which the chips are trapped and rotated about with the rotation of the knife blades for intermittent purging. The knife is formed with relieved areas at the radially inner ends of the blades to provide a region of communication, adjacent the grinding plate, between successive blades to prevent the formation of a central stagnation region and provide that bone chips missed by one blade may be acted upon by another to move chips outwardly.
