The second fixing ring 5061 is fixedly sleeved on the rotating shaft 203. A plurality of vertical holes 5011 are provided on the side wall at the bottom of the cylinder 501. When granulation is required to produce a coating product with a fine particle size, the granulation liquid is squeezed out of the screen plate 502 and the material is sheared and granulated by the shearing blade 5062, so that a finer particle product can be produced with higher production efficiency. At the same time, during the shearing process of the shearing blade 5062, the material is thrown to the side wall of the cylinder 501 for further impact and crushing. When the material is thrown to the side wall of the cylinder 501, a part of it passes through the vertical hole 5011 and the other part is blocked by the inner wall, further improving the shearing effect. After the shearing device 506 performs shearing and granulation again, the particle size is smaller and the particle size will not be too uniform. The sprayed color point presentation effect is more realistic with natural stone.

[0035] The paint granulation equipment disclosed in one embodiment also includes a control device 7, which preferably adopts a PLC control system.
