Abstract:
An apparatus for grinding spherical objects into an exact spherical shape comprising at least a grinding section equipped with means for grinding spherical objects, an inlet section equipped with means for feeding spherical objects to the grinding section and an outlet section equipped with means for taking out reshaped spherical objects from the grinding section, said inlet section, grinding section and outlet section communicating by transporting means, whereinsaid transporting means comprises an endless carrier belt having a series of apertures made for accepting and carrying therein spherical objects and a drive for driving the endless carrier belt; said means for grinding spherical objects comprises an endless grinding belt separate from and positioned beneath the endless carrier belt wherein the endless grinding belt is parallel relative to the endless carrier belt and travels in either one of a same or counter direction relative to the endless carrier belt, a flat support positioned beneath the endless grinding belt to slidably support the endless grinding belt, and a randomizer positioned above the endless carrier belt that is capable of moving back and forth across the endless carrier and grinding belts to sandwich the spherical objects between the randomizer and the endless grinding belt.
