Water-based paint raw material grinding machine and using method thereof

The invention provides a water-based paint raw material grinding machine and a using method thereof, and belongs to the technical field of water-based paint processing.The water-based paint raw material grinding machine comprises a lower grinding disc, a driving motor and an upper grinding disc connected with an output shaft of the driving motor, and further comprises movable grinding sliding blocks movably arranged on the inner side of the lower grinding disc and evenly distributed in an annular mode; when the upper grinding disc rotates to a grinding convex block arranged at the bottom of the upper grinding disc and passes through the movable grinding sliding block, the movable grinding sliding block can be pushed towards the interior of the lower grinding disc, and meanwhile the extrusion stress between the movable grinding sliding block and the grinding convex block can be increased through the elastic force of a spring set arranged between the movable grinding sliding block and the lower grinding disc.
