Import Ball Mill Head Trunnion Manufacturer — Buy in Bulk from Supplier in China

The Ball Mill Head Trunnion from Great Wall Steel Casting Co., Ltd. is a cast steel component designed to support the rotating cylinder of a ball mill while serving as the inlet and outlet channel for materials. This part is engineered to withstand significant bending forces during operation, with a typical weight range of 5 to 30 tonnes. The material specification is ZG230-450, a standard carbon steel grade for heavy-duty casting applications in grinding equipment.

Manufactured using steel casting techniques, the trunnion integrates seamlessly with the mill’s bearing pedestal and girth gears, ensuring stable rotation under high loads. The ZG230-450 grade provides a balance of strength and machinability, with typical tensile strength values in the 450-550 MPa range for this class of casting. Surface finish and dimensional tolerances are controlled to standard milling industry requirements, with custom machining available to match user-provided drawings.

This component is primarily used in cement, metallurgy, and building materials industries where ball mills are deployed for grinding ores, clinker, or raw materials. Buyers typically source these trunnions for new mill installations or as replacements for worn parts in existing operations. The supplier offers customization based on technical drawings, allowing adaptation to specific mill designs or operational loads.
