A concrete grinder generally contains a rotating head that is used to smooth and level the concrete surface. Nowadays, the use of such tools is growing rapidly, most of the concrete grinding is done by diamonds. This process is known as "diamond grinding" as the abrasive discs utilized to grind the surface contain diamond particles.

The size of the grinding media is calculated based on the grinding capacity of the mill and the size of the feed material. Because of the complex movement of the grinding media and the material in the mill, and because the actual production situation of each cement plant is different, it is difficult to determine a universally applicable grading rule.

The grinding of materials is more sufficient. In the raw mill grinding process, the grinding material is discharged from the grinder through the discharge hole, and the fineness of the qualified material is sorted by the sorting equipment, while the fineness of the unqualified material is sent back to the cement raw mill by the sorting machine.
