GRINDING HEAD OF PLANOGRINDING MOBILE MACHINE Russian patent published in 2009 - IPC B24B7/22 B24B7/18 

FIELD: machine building.

SUBSTANCE: invention is related to the field of machine building and may be used in processing of hard concrete, mosaic and similar surfaces, in particular, for grinding of stone floors. Grinding head is designed for installation of planogrinding mobile machine. Every abrasive element of head consists of trapezoidal body and diamond-containing segments. The latter are located in plane of trapezoidal body, which is inverted to the side of processed surface, with creation of angle between longitudinal axes of mentioned segments and abrasive element, and the angle top is directed to the side of grinding head rotation axis.

EFFECT: such design increases grinding head resource and increases quality of processing, since it provides free outlet of sludge from grinding zone under action of centrifugal forces.
