BALL MILL TRUNNION

The ball mill trunnion is the key component to support and connect the cylinder, and it is the passage of material in and out. The journal bears mainly the bending force during operation. The trunnion neck that is in contact with the spherical bush of the ball mill and the arc neck that is in connection with the cylinder must not have casting defects of pores and sand holes. And the part that is in contact with the spherical bush needs to be ground to ensure accuracy and smoothness.

Jieshengyuan adopts high-strength steel and unique heat treatment technology, so that the ball mill trunnion has high hardness and strong impact resistance, which can greatly ensure the long-term stable operation of the trunnion.
