Grinding apparatus

A grinding apparatus configured to grind a substance to be ground, the grinding apparatus comprising:

• a rotating body configured to include therein a channel extending up to an opening formed in an outer peripheral surface of the rotating body, the rotating body being configured to be capable of accommodating in the channel the substance and a grinding medium capable of grinding the substance;
• a grinding container configured to include therein:
• an accommodation space accommodating the rotating body;
• and
• an opposed surface opposed to the opening of the rotating body, the opposed surface extending annular about a center axis of the rotating body;
• and
• a moving mechanism configured to move the substance and the grinding medium that are separated from the rotating body into the channel of the rotating body again, wherein
• the grinding medium and the substance are capable of being moved from the channel to the accommodation space through the opening by rotating the rotating body.

• an opposed surface opposed to the opening of the rotating body, the opposed surface extending annular about a center axis of the rotating body;
• a removal unit that is located between the opposed surface and the rotating body so as to be opposed to the opposed surface in a radial direction of the rotating body;
• and
• a moving unit configured to move the removal unit in a circumferential direction of the opposed surface, wherein
• the grinding medium and the substance are capable of being moved from the channel to the accommodation space through the opening by rotating the rotating body, and
• the removal unit is moved by the moving unit to come into contact with the substance deposited on the opposed surface and remove the substance deposited on the opposed surface.
