The Semi-Autogenous Grinding (SAG) Mill is one of the core pieces of equipment in large-scale mining projects, placing high demands on structural strength, manufacturing precision, and long-term operational reliability. Leveraging its mature production system and extensive experience, Shenyang Sanland Mining Engineering Co., Ltd. delivers comprehensive SAG mill manufacturing solutions that ensure stable and efficient operation.

Key components of the Sanland SAG mill include the finished hollow shaft, which serves as a critical load-bearing and transmission element. Manufactured from high-quality materials and processed with strict dimensional control, the hollow shaft ensures accurate alignment and reliable performance during continuous operation. In addition, girth gear machining is carried out with close attention to tooth profile accuracy and meshing quality, enabling smooth power transmission, reduced noise, and extended service life.

The shell and flange welding process is another essential step in SAG mill fabrication. Sanland applies standardized welding procedures combined with inspection and quality control measures to ensure structural integrity, concentricity, and overall stability. This robust construction provides a solid foundation for subsequent assembly and long-term heavy-duty operation.

In mining and mineral processing plants, SAG mills are primarily used in the coarse grinding or primary grinding stage, capable of handling large feed sizes and simplifying grinding flowsheets. They are often combined with ball mills to form SAB or SABC circuits, improving throughput and overall system efficiency.

With more than 30 years of experience in mining equipment manufacturing, Sanland offers reliable SAG mill solutions tailored to different ore characteristics and process requirements.
