NOVELTY - A ground material is manufactured by introducing to-be-pulverized raw material into cylindrical-shaped space (21) of container (A) (1) of vibrating mill (100), vibrating, and grinding raw material. Vibrating mill is equipped with component (A) maintained with respect to central axis at vertical surface direction to allow vibration and has cylindrical-shaped space at horizontal surface direction, greater than or equal to 1 cylindrical media (B) (2) arranged parallel to central axis of cylindrical-shaped space of component (A) to allow vibration, and 2 rod-shaped media (C) (3).    USE - Manufacture of ground material for reinforcing agent of cosmetics, foodstuff, biomass material, and resin.    ADVANTAGE - Crystalline raw material to be pulverized is made amorphous for a short time, and productivity of ground material manufacture can be improved.    DETAILED DESCRIPTION - A ground material is manufactured by introducing to-be-pulverized raw material into cylindrical-shaped space (21) of container (A) (1) of vibrating mill (100), vibrating, and grinding raw material. Vibrating mill is equipped with component (A) maintained with respect to central axis at vertical surface direction to allow vibration and has cylindrical-shaped space at horizontal surface direction, greater than or equal to 1 cylindrical media (B) (2) arranged parallel to central axis of cylindrical-shaped space of component (A) to allow vibration, and 2 rod-shaped media (C) (3) arranged to become inside of component (B) parallel to central axis of cylindrical-shaped space to allow vibration. Ratio of total length of center axis direction of component (B) to length of center axis direction of cylindrical-shaped space of component (A) is 0.8-0.995. Ratio of length of component (C) to length of center axis direction of cylindrical-shaped space of component (A) is 0.8-0.995. Total value of the volume of component (C) is 20-25% with respect to total value of the interior volume of component (B).    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a vibrating mill.
