A feed control adapter operable for effecting the regulation of the flow of ball bearings to a ball grinding machine. The adapter is intended to be installed upstream of a ball grinding machine and includes first and second flow regulating devices and an automatic ball flow shut-off. The first and second ball flow regulators may be actuated either independently of each other or in concert. The automatic ball flow shut-off becomes operative when an excess number of balls are delivered to the entrance of the grinder feed chute as a result of the action of the balls themselves which function as a valve to stop the feed of the balls.
