At the same time, the conical design is adopted so that when the height of the grinding roller changes, the distance between the outer surface of the grinding roller and the inner surface of the grinding chamber changes synchronously.

[0010] Furthermore, a feed port is provided at the top of the grinding cylinder, a top diameter of the feed port is larger than a bottom diameter of the feed port, and the grinding chamber is communicated with the feed port.

[0011] The beneficial effect of adopting the above further solution is that it facilitates the entry of materials into the grinding chamber.

[0019] The beneficial effect of adopting the above further solution is that the motor can be reinforced by the fixing frame, which can reduce the shaking of the motor during operation.

[0020] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0021] The gypsum powder grinding mechanism is provided with a grinding cylinder in a cylinder, a conical grinding chamber in the grinding cylinder, and a grinding roller adapted to the inner shape of the grinding cylinder in the grinding chamber. When in use, it is only necessary to adjust the height of the grinding roller by an electric telescopic rod to change the distance between the outer surface of the grinding roller and the inner surface of the grinding chamber, thereby grinding gypsum powder of different particle sizes. This solves the problem in the prior art that the distance between the movable grinding table and the fixed grinding table of the grinder is fixed, resulting in the inability to adjust the particle size of the ground gypsum powder, and thus it is difficult to adapt to the production and processing requirements of gypsum powder of different particle sizes.
