The manufacturing of a girth gear for a Semi-Autogenous Grinding (SAG) mill at Shenyang Sanland Mining Engineering Co., Ltd. has reached another important milestone. The gear hobbing process has been successfully completed, and the component has now entered the drilling stage.

As a key transmission component of the SAG mill, the girth gear plays a crucial role in transferring power from the drive system to the mill shell. Its machining accuracy directly affects operational stability, transmission efficiency, and long-term reliability of the equipment. The completion of the hobbing process marks a critical step, as precise tooth profile forming ensures that pitch, tooth geometry, and meshing accuracy meet design specifications.

Following hobbing, the manufacturing team has proceeded to the drilling operation. This stage is essential for subsequent assembly and structural connection. Strict positioning control and dimensional inspection are carried out to ensure hole accuracy and alignment, preventing tolerance accumulation and safeguarding overall assembly quality.

SAG mills are widely used in the grinding stage of mining operations, typically positioned after crushing and before ball milling. As an integral part of the drive system, the girth gear’s manufacturing quality is fundamental to achieving smooth and continuous mill operation under heavy-duty working conditions.

Sanland remains committed to precision machining and strict quality control throughout every production stage, ensuring that each critical component meets high manufacturing standards and supports reliable equipment performance.
