だ無機質結晶体粒子を球状化させるものはなかった。These particles are produced through a synthetic reaction, and with silica, for example, it has become possible to obtain extremely uniform, perfectly spherical particles. However, no mechanical method has yet been available for spheroidizing inorganic crystal particles.

問題が避けられなかった。また、合成反応による球状粒
子は品質的には問題はないものの価格的に高くなるため
、その使用範囲が制限されるという点がある。(Problems to be Solved by the Invention) In other words, since powdered products are highly agglomerated and have poor dispersibility, problems such as lack of spreadability and smoothness cannot be avoided when used. Further, although spherical particles produced by a synthetic reaction have no problem in terms of quality, they are expensive, which limits the range of their use.
本発明は、コロガリ性にすぐれ分散性の良好な無機質結
晶体粒子を機械的方法により安価に造り出すことにある
。The object of the present invention is to produce inorganic crystalline particles having excellent rolling properties and good dispersibility by a mechanical method at low cost.
（問題点を解決するための手段）
立方体形状をした無機質結晶体粒子の角を面取りし、そ
の角を丸くすることによって立方体のから球形へと形状
変化させる。(Means for solving the problem) The corners of the cubic inorganic crystal particles are chamfered and the corners are rounded to change the shape from a cube to a sphere.
（作用）
立方体形状をした無機質結晶体粒子に対し、攪拌による
分散と混合の作用を付与させる過程において、強力な押
圧力と摩擦力を加えることにより粒子の角部は押し潰さ

ができる。この粒子は、同操作を繰り返し行わせること
により、次第に球状化されて行く。(Function) In the process of dispersing and mixing cube-shaped inorganic crystal particles by stirring, the corners of the particles are crushed by applying strong pressing force and frictional force. In addition, since the portion is transferred to the surface portion and kneaded into the particle, uniform and substantially spherical particles without corners can be obtained by repeatedly applying the above-mentioned dispersion and mixing actions. By repeating the same operation, the particles gradually become spherical.
（発明の効果）
こうしてできた無機質結晶体粒子は、滑りがよく分散性

常に安価になる。(Effects of the Invention) The inorganic crystal particles thus produced have good slippage and excellent dispersibility, and provide good uniform mixing and kneading properties during use. In addition, it is very inexpensive because it can be easily produced from cubic particles, which are much cheaper than spherical particles produced by synthetic reactions.

できた。Next, the operation will be explained. After the raw material is put into the rotary container 1, the rotary container 1 is rotated at high speed, and the raw material inside is pressed against the inner peripheral surface 2 of the container by centrifugal force to form a powder layer of the raw material. A friction piece 3 and a scraping piece 4, which are attached to the rotary container 1 so that they can freely rotate relative to each other, are pressed against this, and compression and friction by the friction piece 3 and dispersion and mixing by the stirring action of the scraping piece 4 are repeatedly applied. As a result, the corners of the cube-shaped raw material particles were crushed and rounded, and the particles were transformed into particles with no corners and a shape that easily crumbled.
