摘要： It is an object to provide a granular body grinding device capable of grinding granular bodies efficiently and excellently and to provide a foundry sand reclamation device and a particulate generating device to which the granular body grinding device is applied.
A granular body grinding device comprises a case 10 for containing granular bodies 2; a drive shaft 23 supported by the case 10 to be rotationally drivable; a grinding disc 30 having a disc-like disc main body 31 that is fixed on the drive shaft 23 and that is formed with disc surfaces perpendicular to the axial direction of the drive shaft 23, and formed with a grinding surface 32 at the disc surface of at least one of the disc surfaces on both sides of the disc main body 31; and fluidizing means 40 for fluidizing the granular bodies 2 in a floating state by sending air from the a bottom surface portion of the case 10, to form a fluidized bed S in which at least a part of the grinding surface 32 is soaked.
