Wear is part of the process. The challenge is keeping it under control.
In an impact crusher, blow bars are where energy meets the feed material — and where significant mechanical stress begins.
Their shape and material, together with rotor speed and impact apron settings, influence how they wear and how long they remain effective. That makes wear more than a maintenance issue. It can affect spare parts consumption, maintenance requirements and ultimately plant availability.
Swipe through facts 17 to 20 and take a closer look at blow bars, wear and the factors that influence both.
What plays the biggest role in managing wear in your experience: material properties, operating parameters or blow bar selection?
