ARRANGEMENT FOR PROCESSING SMALL BALLS OUT OF SEMIPRECIOUS STONES Russian patent published in 2007 - IPC B24B11/08 

FIELD: the invention refers to the field of abrasive processing.

SUBSTANCE: it may be used in jewel industry at manufacturing semi-finished products of a spherical form - small balls out of semiprecious and jobbing stones, for example, out of amber. A profile grinding disk, a unit of circular feeding of small balls and a unit of transporting small balls into a working zone are mounted on the founding. A bunker is envisaged for automatic loading of the small balls into the unit of transporting them into the working zone. The last is fulfilled in the shape of a separator with pockets. The separator is mounted in the body with possibility of independent rotation. The unit of circular feeding of small balls is fulfilled in the shape of two driving rollers having independent one from another rotation and coaxially located along the both sides from the separator.

EFFECT: such construction increases productivity and quality of processing small balls due to continuity of the process and giving the small balls multiaxial rotation.
