Ball Miling Liners

Ball mill liner blocks are wear-resistant liners installed inside the ball mill to protect its inner wall from wear and impact. These liner blocks are typically made of wear-resistant materials such as wear-resistant steel plates and wear-resistant alloys, offering high wear resistance and impact resistance. They effectively resist the wear and impact of the ore inside the ball mill, prolonging its service life. The installation of ball mill liner blocks is usually done through welding or bolt connections. During installation, attention should be paid to the dimensions, shapes, and positions of the liner blocks to ensure effective protection of the ball mill's inner wall.

Our company has been conducting research and development on high-manganese steel liners for over 20 years. We produce various ball mill liners ranging from Φ1.5×3M to Φ7.32×10.68M. Based on the wear trajectories of different mill models, we further optimize the shape and material of the liners, continuously improving their service life. For example, the service life of liners for Φ3.2×3.1M, Φ3.2×4.5M, and Φ5.03×6.4M ball mills exceeds 10 months, while the liners for Φ7.32×10.68M ball mills can reach up to 16 months. The operational efficiency of the ball mills has been significantly improved, earning consistent praise from our customers.

The standard hardness ranges from HB180 to 220, with a tensile strength (Rm) of ≥735MPa and an elongation rate of ≥20%.
