Abstract

See full text

A granular body grinding device includes a case for containing granular bodies; a drive shaft supported by the case to be rotationally drivable; and a grinding disc having a disc-like disc main body that is fixed on the drive shaft and that is formed with disc surfaces perpendicular to the axial direction of the drive shaft, and formed with a grinding surface at the disc surface of at least one of the disc surfaces on both sides of the disc main body. The grinding device further includes a fluidizing device for fluidizing the granular bodies in a floating state by sending air from the bottom surface portion of the case, to form a fluidized bed in which at least a part of the grinding surface is soaked.
