Recently, new progress has been made at Sanland’s heavy equipment manufacturing facility, where a 5.5-meter diameter SAG (Semi-Autogenous Grinding) mill shell has entered a critical stage of production. The overall manufacturing process is advancing smoothly and according to schedule. From the on-site view, the main structure of the shell has been formed, with a smooth surface finish and evenly distributed holes, reflecting high machining quality and precision.

As one of the core structural components of a SAG mill, the shell plays a vital role in supporting both ore and grinding media while withstanding continuous impact loads and abrasive conditions during operation. Therefore, strict requirements are placed on its structural strength, welding quality, and machining accuracy, all of which directly affect the stability and service life of the entire machine.

In terms of manufacturing processes, the 5.5m SAG mill shell undergoes multiple key stages, including plate cutting, rolling, welding assembly, post-weld heat treatment, and precision machining. Particularly during welding and subsequent machining, careful control of process parameters and sequencing ensures the roundness, concentricity, and hole accuracy of the shell, providing a solid foundation for final assembly.

At the current stage, the shell has completed main welding and preliminary machining and is undergoing hole machining and surface finishing. Due to its large size, heavy weight, and complex structure, the component requires advanced equipment and extensive manufacturing experience. Sanland leverages its expertise in heavy-duty equipment production and standardized workflows to ensure stable quality and efficient process coordination.

SAG mills are widely used in the grinding stage of mining operations, capable of processing larger feed sizes and reducing the need for extensive upstream crushing. This contributes to improved operational efficiency and reduced overall energy consumption. The reliable manufacturing of large-scale SAG mill components is essential for ensuring the success of mining projects.

The smooth progress of this 5.5m SAG mill shell once again demonstrates Sanland’s strong capabilities in heavy mining equipment manufacturing. Moving forward, the company will continue to enhance its production standards and deliver efficient and reliable solutions to customers worldwide.
