Introduction

The mill trunnion is an important part that carries the rotation of the ball mill cylinder. Generally, mill trunnion applies high-quality 35# cast steel which has relatively high casting requirements. There shall be no casting defects of pores and blisters in the neck contacting the spherical surface tile of the ball mill and the arc neck contacting the cylinder body. In terms of processing, the part in contact with the spherical surface tile needs to be ground after processing to ensure accuracy and smoothness.
The ball mill trunnion produced by AGICO Cement has a complete range of specifications and models, and integrated casting and processing. We can provide high-quality ball mill trunnion for the majority of ball mill manufacturers and mill trunnion with special specifications can be customized.

Advantages of AGICO’s ball mill trunnio

1.The fracture of the ball mill trunnion is a relatively easy problem to encounter, but no such problems have been found among the products of AGICO which shows that our mill trunnion has excellent, stable and reliable quality.

2.Ball mill trunnion, as the key component of the cement machinery, is a special steel casting part. The weight of the whole machine mainly plays the role of supporting and ligating the cylinder, and is the channel for material discharge. At the same time, it must bear the main shaft when working.

3.The root ball of the side disk is the defects of blisters, pores and micro-cracks that are easy to appear in the casting parts when the stress of the mill trunnion is concentrated. In order to solve the problems that have plagued the company for many years, our company has introduced the casting process simulation technology and improved the casting process of the mill trunnion:

1. Strengthen the hardness of mill trunnion by 30% compared to its counterparts
AGICO Cement adopts unique heat treatment technology, which improves the hardness of the mill trunnion and enhances the impact resistance;

2. Prolong the service life of mill trunnion by 50% compared to its counterparts
The mill trunnion of AGICO machining is made of high-strength steel. In the early stage of casting, professional engineers optimize the process structure according to the operating characteristics of the ball mill to ensure the stability of the part under long-term operation to extend the service life of components.

3. AGICO Cement has a large casting basein China.
Which can manufacture mill trunnion and other components in large quantities with short production cycle and large output.
