A slurry treatment material containing solid particles mixed in liquid is finely pulverized, without using dispersion media, by flowing the treatment material into a vessel and through an annular fine gap formed between an inner wall of the vessel and an outer periphery face of a rotatable body mounted within the vessel. Rotation of the rotatable body subjects the treatment material to compression, expansion and shearing treatments. After passing through the annular fine gap, the treatment material flows into an ultrasonic chamber where it is irradiated with ultrasonic waves that break up and disintegrate agglomerated clumps of solid particles that may be present in the treatment material.
