The spherical bearing bush for mineral processing ball mill, also known as the bearing bush for mineral processing ball mill, is a key component that supports the rotation of the mineral processing mill cylinder. It is widely applied to grate ball mills and overflow ball mills, and is made of tin-based Babbitt alloy with a soft matrix and hard particles. The bush is integrally cast and machined with the arc surface of the bearing housing, featuring appropriate hardness, a low friction coefficient, good plasticity and toughness, as well as excellent thermal conductivity and corrosion resistance. For these reasons, it is widely used in mineral processing ball mills.
