Abstract
A refiner includes a main body, a rotation shaft provided inside the main body, a tapered rotor attached to the rotation shaft with a space therein, a stator provided in the main body, a rotor beating portion provided on the rotor and having a groove between bars and through-holes, a stator beating portion on the stator with a groove between bars and through-holes, a raw material supply portion for supplying a raw material into the main body, and a raw material discharge portion for discharging a beaten raw material outside the main body. A portion of the raw material guided to a small-diameter opening portion of the rotor and the space of the rotor is beaten by passing through the through-holes of the rotor beating portion and the stator beating portion, and is discharged outside the stator beating portion from the through-holes of the stator beating portion.
