Grinding Mill Trunnion End

Grinding Mill trunnion end refers to a hollow structure of the shaft, it is one of the important components of the ball mill, the main role of the bearing ball mill cylinder rotation, usually by the shell, lining, supporting structure and other parts. Hollow shaft is used frequently in ball mill, generally made of cast steel or forged steel, after high temperature quenching and tempering treatment, it has high hardness and strength.

FAQ

Q: What is the function of a Grinding Mill Trunnion End?

A: The Trunnion End supports the mill shell at both feed and discharge sides, transferring the load to the main bearings and ensuring stable rotation under heavy material and grinding media loads.

Q: What materials are used for manufacturing the Trunnion End?

A: We use high-strength cast steel or alloy steel, heat-treated to improve hardness and toughness, allowing it to withstand hundreds of tons of load and repeated impact.

Q: How do you protect the Trunnion End from wear?

A: The internal surface is fitted with replaceable wear liners or bushings, reducing abrasion and extending the service life compared with unlined designs by 1.5–2 times.

Q: How precise is the machining of the Trunnion End?

A: Critical surfaces are machined with high precision to ensure concentricity with the mill shell and bearings, minimizing vibration and reducing bearing load.

Q: Is maintenance or replacement convenient?

A: Yes. Many Trunnion Ends are designed in modular or split sections, which allows for easier inspection, maintenance, and liner replacement, reducing downtime significantly.
