Ring armor for rotor centrifugal crusher, has multiple impact segments, where each impact segment has impact wall and rear wall, and impact wall is longer than rear wall

摘要

The ring armor has multiple impact segments, where each impact segment has an impact wall and a rear wall. The impact wall is longer than the rear wall. The rear wall is tilted towards the trajectory of the particles crushed in the direction of the impact wall. The contact intermediate angle between the impact wall and rear wall is less than the intermediate angle between the trajectory of particles and the impact wall at the contact point between the impact wall and rear wall. The rear wall is tilted towards the trajectory of the particles crushed in the direction of the impact wall, and hence ensures to avoid slip motion and has optimal distance between centrifugal rotor external radius and ring armor internal radius that minimizes impacts between particles and centrifugal rotor housings.
