The selection and design of mill liners. Dramatic shortcomings of mill liner designs, especially of large SAG mills, such as rapid failure and even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life have ...

The diameter of a ball mill has a great influence on the power consumption of the mill and thus on the possible production output. This is because the ratio of the diameter to the grinding path length determines the residence time of the material in the mill and thus the theoretically achievable fineness of the material at the discharge.

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

In very large ball mills, these effects generally lead to reduced design criteria. In the case of very large castings, for example, the adoption of relatively high stress range criteria also requires that a relatively high standard of manufacture be achieved. This may be possible, but may also increase the risk of rejecting the casting, with
