The Influence of Alloy Composition on the Performance of Wet Ball Mill Liners
In China's metallurgical mines (such as iron, copper, lead-zinc, and gold mines), wet ball mill liners are primarily made from conventional high-manganese steel materials, while a few enterprises have adopted liners containing high-chromium or ultra-high-manganese steel. These mine-based wet ball mill liners operate under extremely demanding conditions, requiring them to withstand corrosion, impact, and abrasion simultaneously. High-manganese steel liners are renowned for their excellent impact toughness and resistance to impact forces, but they tend to perform less well in terms of wear resistance and corrosion protection.

The swing jaw refers to the movable jaw plate in a jaw crusher. A jaw crusher is a heavy-duty industrial machine used to crush rocks and other materials. The swing jaw moves back and forth, pressing material against the stationary jaw plate—and essentially serves as the machine's "active" crushing component.
