What are the benefits and adjustment principles of material accumulation inside the rotor of a vertical impact crusher

The rotor is the core component of a vertical impact crusher, where materials are primarily crushed and shaped. In actual production, material accumulation inside the rotor is a normal phenomenon. However, the amount of accumulation must be appropriate; excessive or insufficient accumulation can affect component performance and, consequently, normal production.

A. Benefits of appropriate material accumulation inside the rotor:   

1. Material accumulation in the rotor of a vertical impact crusher protects the inner wall of the rotor, and more importantly, protects the rotor discharge head from direct wear and impact, thereby protecting wear-prone components without obstructing material flow through the vertical impact crusher;   

2. If material accumulation inside the rotor is optimal, wear on the upper and lower wear plates is uniform, allowing the rotor discharge head to be fully utilised, thereby reducing production costs.  

B. Preventive measures:

1. Material accumulation should not come into contact with the side walls or bottom of the feed hopper to prevent premature wear;  

2. Ensure that the material flow into and out of each discharge port is consistent to ensure similar wear on the discharge heads.  

C. Basic principles for adjusting material accumulation   

1. Material accumulation inside the rotor should protect wear components without obstructing material flow through the crusher.  

2. Material accumulation should not come into contact with the side walls or bottom of the feed cylinder to prevent premature wear.   

3. Material flow into and out of each discharge port should be consistent to ensure similar wear levels on the discharge heads.
