Claims

[Scope of utility model registration request]

The granular material fed onto a rotating table is crushed and crushed by multiple rollers or balls,
The fine pulverized material is transported to the air classifier by the gas flow introduced upward from the gas passage around the periphery of the table, and the granular material that has fallen from the periphery of the table is discharged outside the pulverizer and returned to the pulverizer table. In the external circulation type vertical crusher, at least a portion below the outer peripheral gas passage of the table, between a point directly below the roller axis and a point moved in the table rotation direction by the roller radius to a point directly below the adjacent roller axis. A vertical crusher characterized in that a downwardly inclined plate toward the table drive shaft is provided in a part of the section to prevent damage from blowing through the gas table outer circumferential passage, but not to prevent granular materials from falling.
