Mill liner replacement is a critical maintenance task in mining operations. Traditional methods are not only costly and hazardous but also result in extended downtime that significantly impacts overall plant productivity. The seven-axis mill liner handler provides a safer and more efficient solution for maintaining large grinding mills such as SAG mills and overflow ball mills, etc,. It substantially reduces liner replacement time, minimizes manual operation risks, and enhances overall equipment operating efficiency.

ec@shyychina.comContinuous innovation driving liner replacement technology
With our deep understanding of on-site operational requirements and thorough research into actual liner replacement scenarios, our liner handler has evolved into the seven-axis mill liner handler. With breakthroughs in flexibility, control accuracy, and working range, it is capable of handling liner replacements for weights ranging from 1 to 5 tons. This versatility has made it the preferred choice for many domestic mining enterprises while also gaining broad recognition in international markets.
As a specialized lifting device, the liner handler uses a hydraulic system to drive the main beam, which moves along tracks or via wheeled ground travel, accurately extending into the mill shell to remove worn mill liners and install new ones. Its unique seven-axis design expands the robotic arm’s range of motion, making liner grasping, shifting, and alignment smoother and more efficient. Throughout the process, the liner handler works in coordination with a liner transport cart to ensure a seamless and continuous workflow.
