[0004] However, in the actual use of the above scheme, due to the uncertainty in raw material grinding, only most of the raw material particles can be ground.

[0005] To this end, the utility model provides a coating grinding device. Utility Model Content

[0015] Furthermore, a handle is fixedly connected to the outer side of the bottom end of the second discharge pipe;

[0016] Through the above technical solution, the handle is fixed by the second discharge pipe, so that the second discharge pipe can be driven to rotate by rotating the handle.

[0017] Furthermore, a cold water tank is provided inside the grinding cylinder;

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The paint grinding device described in the utility model uses a screening plate to transport raw material particles that do not meet the size requirements after grinding back to the top of the grinding wheel through a feed port, a feed pipe, a delivery pump, a delivery pipe and a first discharge pipe, and grinds the raw material particles again through the grinding wheel to make them more in line with product specifications.
