なければならないという欠点が生じる。(Prior art and its problems) A sand grinder that has recently been widely used in the paint, chemical, and ceramic industries has the structure shown in FIG.
By rotating at a high speed (1000 to 3000 rotations), the alumina ceramic cobblestones 2 are thrown off against the outer wall 3, and this repetition exerts a strong shearing force on the raw materials to uniformly knead and disperse them. However, since the conventional rotary disk is made of metal, the outer periphery of the disk is abraded due to the alumina ceramic boulder 2 being thrown off, and the abrasive metal is mixed into the raw material as an impurity. There is also a method of using alumina ceramics instead of metal, but in this case, since the boulders are also made of alumina ceramics, there is a drawback that the stones become sluggish and wear heavily and must be replaced every two days.

We devised a rotating disk using elastic rubber material. However, rotating disks made of rubber are soft and therefore have poor torque impact resistance, resulting in damage to the parts that come into contact with the rotating shaft. As an improvement on this, a rubber material was attached to the metal and used, but the high speed rotation resulted in the drawback that the rubber material peeled off from the metal. Furthermore, among rubber materials, neoprene rubber, nitrile rubber, and the like have the disadvantage that when used in a solvent such as trichlorethylene or perchlorethylene, they are exposed to the solvent and expand.
