## Abstract

An abrasive grain-milling unit and a friction grain-milling unit are located on upper and lower portions of a pedestal, respectively. The friction grain-milling unit includes a grain feed trough to which a milled grain discharge trough of the abrasive grain milling unit is connected. A two-way grain feed trough and change-over valve is located above the abrasive grain-milling unit and is capable of selectively feeding grains either directly to the friction grain-milling unit or to the friction grain-milling unit via the abrasive grain-milling unit.

## Claims

### Claim 1

A grain-milling machine comprising:
a vertical abrasive grain-milling unit,
a vertical friction grain-milling unit,
a two-way grain feed trough, and
a change-over valve located above the two-way grain feed trough, wherein
the two-way grain feed trough is located above the abrasive grain-milling unit and the friction grain-milling unit,
the abrasive grain-milling unit is located above the friction grain-milling unit,
the abrasive grain-milling unit and the friction grain-milling unit are top-down vertical feed units,
the abrasive grain-milling unit includes a milled grain discharge trough,
the friction grain-milling unit includes a grain feed trough to which the milled grain discharge trough of the abrasive grain milling unit is connected, and
the change-over valve selectively feeds grains in the two-way grain feed trough in a vertical feed direction either directly to the friction grain-milling unit or directly to the abrasive grain-milling unit.

### Claim 2 (depends on 1)

A grain milling machine according to claim 1, wherein
the abrasive grain-milling unit comprises a bran removal chamber, a bran discharge trough located below the bran removal chamber, and a pulley having a fan structure to generate air flow during rotation thereof, the pulley being interposed between the bran removal chamber and the bran discharge trough, and
the friction grain-milling unit comprises a bran removal chamber to which the bran discharge trough of the abrasive grain-milling unit is connected, a bran discharge trough located below the bran removal chamber of the friction grain-milling unit for collection and discharge of bran from the abrasive and friction grain-milling units, and a pulley having a fan structure to generate air flow during rotation thereof, the pulley being interposed between the abrasive and friction grain-milling units.
