Claims1
A refiner for beating a raw material, the refiner comprising:
- a rotating shaft extending in an axial direction;
- a rotor beating part including:
- a main body attached to the rotating shaft, and
- a rotary blade on an end face of the main body, the rotary blade extending from an outer periphery of the main body toward the rotating shaft in a radial direction of the rotating shaft;
- a stator beating part including:
- a first ring-shaped body, and
- a fixed blade on an end face of the first ring-shaped body facing the main body, the fixed blade extending from a center of the end face to an inner periphery of the first ring-shaped body, wherein a tip of the fixed blade and a tip of the rotary blade overlap each other in the axial direction;
- and
- a second ring-shaped body positioned on an outer side of the first ring-shaped body in the radial direction, the second ring-shaped body including a slit for discharging the raw material beaten by the stator beating part and the rotor beating part.
