Technical Field

[0001] The utility model relates to the technical field of cement mills, in particular to a flow stabilizing device for cement mill grinding aids. Background Art

[0002] In the mill, cement material needs to be ground and sheared many times to achieve the required fineness and particle size distribution. Grinding aids can effectively improve the surface properties and structure of the material, thereby improving the grinding efficiency and fineness control of the mill. The high-fineness grinding process is a more detailed and precise grinding method. By optimizing the material flow and shearing inside the mill and developing and using grinding aids, more efficient and finer grinding effects can be achieved.
