Title:
PULVERIZER
Document Type and Number:
Japanese Patent JP3657104
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To pulverize a coarse grain particle by a method wherein one side of a through hole of a rotary cylindrical body is made to be a supply side of a material to be pulverized, its opposed side is made to be an outlet, a groove formed radially from a rotary center is disposed on the surface at the outlet part, and face plates rotating in opposed directions by facing each other are arranged.
SOLUTION: Fixed cylindrical bodies 1b, 2b wherein a groove is formed in the direction of the generating line on an inside surface are arranged to the outside of rotary cylindrical bodies 1a, 2a, one sides of through-holes 3, 4 formed at rotary axis centers of those rotary cylindrical bodies 1a, 2a are made to be a supply side of a material to be pulverized, and the opposed sides are made to be outlets 1d, 2d. Further, the groove formed radially from a rotary center is formed on the surface at the outlet parts 1d, 2d, and face plates 5, 6 rotating in the opposed direction to each other are arranged. Since a coarse grain raw material repetitively receiving pulverizing action by colliding with inclined faces of the groove of both face plates 5, 6, thereby, the coarse grain particle can be pulverized.
