Description

TECHNICAL FIELD The present invention relates to a grain refiner.

(Prior Art) In the publicly known Japanese Patent Publication Nos. Sho 32-8660 and Sho 33-64, techniques for grinding (polishing) and then polishing (friction) are described.

The above-mentioned machines are classified into a grinding machine and a friction machine, but a machine having a uniaxial shape is also described in JP-B-47-652 and is known.

(Problems to be Solved by the Invention) The former has a complicated structure because the grinding polishing machine and the friction polishing machine are separate from each other. The latter has a simple structure due to its uniaxial shape, but grain is distributed only in the lower part due to the horizontal axis, so squatting is unavoidable. Further, the grinding speed and the friction grinding speed are different from each other even though the rotation speeds thereof are totally different from each other.

However, it is possible to obtain a grinding and friction polishing device having a small structure, even if the vertical axis is distributed all around.

(Object of the invention) Therefore, the present invention is intended to prevent the polishing of the vertical axis and to reduce the size of the vertical axis so that the polishing can be performed according to the purpose of the fine grain.
