Patent ID: 7631826

Claim:
A crushing apparatus comprising: a supplying section for receiving a solid material; at least one crushing section for crushing the material supplied from the supplying section; and a discharging section for discharging the material crushed by the crushing section to outside; wherein the at least one crushing section is defined between a rotating disk on a side of the supplying section and a rotating disk on a side of the discharging section, the rotating disks being connected to at least one rotating shaft to be driven to rotate and arranged at positions spaced apart from each other in an axial direction; wherein at least one of the rotating disk on the side of the supplying section and the rotating disk on the side of the discharging section is arranged with at least one blade projected from a face thereof and is formed with at least one through hole penetrated in the axial direction at a position proximate to a rotational axis center of the rotating disk; wherein the material supplied from the supplying section is crushed as the blade in the crushing section is driven to rotate and the material is discharged to the side of the discharging section on a downstream side of the crushing section via the at least one through hole formed at the at least one rotating disk; wherein a guide disk is positioned in parallel to and between the rotating disks and is connected to the rotating shaft of one of the rotating disks so as to rotatably driven, and wherein the guide disk is formed with a guide face having a shape to guide a powder produced in the crushing section toward the blade as the guide disk rotates.
