The invention discloses a particle damping jigging vibration reduction device of a high-pressure roller type vertical mill. The particle damping jigging vibration reduction device is designed as for the vibration characteristics of the vertical mill and the characteristics of a powder selecting device of the vertical mill. The particle damping jigging vibration reduction device mainly comprises avibration reduction box mounted at the position of a vertical mill center cone body and a damping medium with which the vibration reduction box is pre-filled. When the vertical mill works, coarse powder screened by a powder selector falls into the vertical mill center cone body and enters the vibration reduction box through an upper opening, a vibration reduction damping medium is formed by the coarse powder and the damping medium jointly, and the coarse powder moves along with the damping medium and gradually moves to a porous bottom plate downwards and finally is discharged from an open holein a bottom plate.
