[0019] The working principle of this utility model is as follows: The second drive motor drives the second rotating shaft, pulley, conveyor belt and crushing wheel to rotate. Then, iron oxide red pigment particles are put into the crushing chamber. The crushing wheel will crush the iron oxide red pigment particles to reduce their volume and avoid affecting the grinding effect due to the large size of the iron oxide red pigment particles, thereby improving the grinding efficiency of the iron oxide red pigment particles. Then, the second electric valve is controlled to open the feed pipe. The crushed iron oxide red pigment particles will fall onto the grinding plate of the grinding tank through the feed pipe.
