1. A solid material grinding device with an adjustable discharge size, comprising:
a grinding disc housing provided thereon with a feed inlet, a discharge outlet, a top rectifying blower, a side edge rectifying blower, and a central rectifying blower; and
a movable grinding disc and a stationary grinding disc provided in a grinding disc cavity of the grinding disc housing coaxially with grinding surfaces opposite to each other, wherein
the stationary grinding disc is fixed with the grinding disc housing;
the movable grinding disc is driven by a drive mechanism to rotate in the grinding disc housing, thereby grinding materials between the movable grinding disc and the stationary grinding disc;
the movable grinding disc is further connected to a pushing mechanism;
the pushing mechanism adjusts a distance between the movable grinding disc and the stationary grinding disc in a push-and-pull manner;
the top rectifying blower and the side edge rectifying blower respectively blow gas from an upward side and a lateral side of the movable grinding disc and the stationary grinding disc along a radial direction of the movable grinding disc and the stationary grinding disc; and
the central rectifying blower blows gas to a center of the stationary grinding disc along an axial direction of the movable grinding disc and the stationary grinding disc.
