[0002] In the mining, cement, chemical and other industries, ball mills are key equipment and are widely used in the crushing and grinding process of materials. The liner structure inside the cylinder, its core component, plays a vital role in improving the working efficiency of the ball mill, protecting the cylinder from wear and extending the life of the overall equipment.

[0003] However, the existing ball mill liner fixing method generally relies on bolt tightening. Although this method achieves a stable installation of the liner to a certain extent, it also exposes many disadvantages. First, each liner needs to be fixed with a large number of bolts, which not only increases the complexity and time cost of the installation and disassembly process, but also greatly increases the difficulty of maintenance and repair. Especially when replacing or repairing the liner, a large number of bolts need to be removed and tightened one by one, which not only consumes a lot of manpower, but also prolongs the downtime and affects production efficiency.
