In a ball throwing machine, especially for squash balls or tennis balls, there is located on the base of a ball storage container a ball separating device in the form of a driven turntable which is arranged so as to be rotatable in a substantially horizontal plane and has on a circumferential circle substantially vertical passages of a width somewhat greater than the diameter of the balls to be separated. The turntable has a thickness corresponding to a multiple of a ball diameter and at the ball delivery point it has a ball stop which is located at a distance equivalent to approximately one ball diameter above the base member and there at least partially blocks the passages and for that purpose extends into a peripheral groove of the turntable. Each passage is located above a discrete base member which is connected to the turntable and rotates together with the turntable and gives way selectively below each passage in the peripheral sector of the ball discharge opening.
