[0002] Primer is the first layer of the paint system. It is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat so that the paint system can achieve the best effect.

[0003] A sand mill generally discharges materials through a discharge barrel, but the material fluidity may be poor during discharging, which may cause the material to accumulate in the discharge barrel and block it. Most sand mills for primer production do not have an anti-blocking structure, and the staff is required to manually unclog the discharge barrel, which increases the staff's workload. Therefore, those skilled in the art provide a sand mill for etching primer production with an anti-blocking function, in which an anti-blocking mechanism is installed at the bottom of the discharge barrel. When the material falling speed is slow or blockage occurs, starting the anti-blocking mechanism can automatically stir the material in the discharge barrel, and then unclog the discharge barrel to achieve the effect of automatically unblocking the discharge barrel, thereby reducing the workload of the workers, so as to solve the problems raised in the above background technology.
