Recently, our company successfully completed a custom ball mill drum machining project for a North American mining client. As a professional manufacturer, we leverage our full-scale, in-house production capabilities to meet the client's stringent equipment performance standards.
During the machining process, our large-scale CNC machining equipment played a key role. Its 8-meter travel range enables precision machining of large components, such as the drum body, in a single operation, effectively avoiding the cumulative errors associated with segmented machining. The drum in question has a diameter of 3.2 meters and a length of 16 meters. The CNC system's precise control of the cutting path ensures that machining accuracy in key areas remains within the specified drawing specifications.
In terms of material selection, our technical team selected high-strength, low-carbon alloy structural steel based on the client's operating parameters. Third-party testing confirmed that the material's tensile strength and impact toughness meet North American mining equipment standards. From raw material cutting and welding to heat treatment, finishing, bearing seat assembly, and dynamic balancing testing, all processes are completed independently by our company, fully monitored under the ISO9001 quality management system.
The drum has now entered the final performance testing phase and is expected to be packaged and shipped next month. Customer representatives performing on-site inspections praised the company's fully in-house production model, believing it provides reliable assurance of equipment quality.
