Dispersion and grinding machine

A dispersion and grinding machine comprising a supply portion for supplying a material to be processed, a processing portion for subjecting the material to be processed, which is supplied by the supply portion, to dispersion or grinding processing, and a discharge portion for discharging, from the processing portion, the material that has been processed by the processing portion,

• wherein the processing portion includes a stator having an inner cavity with an inner peripheral surface, and a rotor provided in the inner cavity and rotatable about an axis of the stator, and the material to be processed being processed in a gap between an outer peripheral surface of the rotor and the inner peripheral surface of the stator, the inner peripheral surface facing the outer peripheral surface of the rotor,
• wherein the inner peripheral surface of the stator and the outer peripheral surface of the rotor are concentrically circular in a cross section orthogonally intersecting the axis of the rotor, and linear in a cross section bearing the axis, and the gap between the inner peripheral surface of the stator and the outer peripheral surface of the rotor is constant in the circumferential direction and the axial direction,
• wherein the discharge portion includes a screw rotor for conveying the material that has been processed by the processing portion, an outlet stator that surrounds the screw rotor and includes an insertion hole having a constant inner diameter, and a holding part that holds the outlet stator and has a discharge outlet for discharging the processed material to the outside, the screw rotor being formed with a fin in such a way as to forcibly discharge the processed material with a rotation of the screw rotor, the discharge outlet of the holding part having the same diameter as the insertion hole of the outlet stator, and
• wherein the rotor of the processing portion and the screw rotor of the discharge portion are integrated with each other with their respective axes being aligned and extending in a horizontal direction,
• the dispersion and grinding machine further comprising:
• a single rotating driver for drivingly rotating the rotor and the screw rotor.
