Introduction

Ball mill trunnion (ball mill hollow shaft) is an important part to support rotating ball mill cylinder. It is mainly used to support and connect ball mill cylinder, and is the inlet and outlet channel for materials. Thus ball mill trunnion shaft mainly bears the bending force during operation.

The fillet at the root of ball mill trunnion the stress concentration part, on which sand holes, pores and micro-cracks defects likely occur during casting.

Unit weight: 5-30T

Applications: Cement, metallurgy, building materials and other industries

Main material: ZG230-450
