(Effects) In the publicly known Japanese Patent Publication Nos. Sho 32-8660 and Sho 33-64, there is described a technique of grinding (friction) polishing after grinding and polishing. Since and are different from each other, the structure is complicated. Further, a uniaxial shape is also known and described in Japanese Patent Publication No. 47-652, but since it is a horizontal axis, squatting is inevitable. 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, the present invention is directed to the vertical rotary spindle 10 and the rotary spindle.

And, since it is a grain refining device consisting of a connecting cylinder 34 that moves the grain ground and grained by the grinding grain roll 27 provided at the upper portion of the grinding grain net 31 to the lower feed grain feeding spiral 16, The grain fried by the fried helix 25 is initially crushed by the grinding grain rolling roll 27 to mainly damage the surface of the grain, and the grain whose surface is scratched by the initial grain is mediated by the connecting tube 34. Downward feed grain spiral 16 and downward feed grain cylinder
It is supplied during 20 minutes, and is then sent between the friction rotary refined grain roll 15 and the friction milling net 19 for finishing milling. in the meantime,
The grains are milled in optimum condition with a rotation suitable for the initial and final polishing. In addition, since the initial polishing is performed on the outside and the finishing polishing is performed on the inside centering on one axis, no space is required and the device becomes a small device.

Further, the passive pulley 14 is fixed to the lower part of the vertical rotating main shaft 10, and the passive pulley 26 is integrally formed on the lower part of the fried helix 25.
