Description

Technical Field

[0001] This utility model belongs to the technical field of ball mill liner plates, specifically a ball mill liner plate that is easy to replace. Background Technology

[0002] Ball mill liners are components used to protect the mill cylinder from direct impact and friction by grinding media and materials. They are typically made of medium-alloy steel, possessing high wear and impact resistance. Ball mill liners are widely used in industries such as mining, metallurgy, steel, non-ferrous metals, phosphate fertilizers, coal-water slurry, flue gas desulfurization, and building materials. In addition, rubber liners are also widely used in wet grinding processes, offering advantages such as impact resistance, corrosion resistance, high wear resistance, and low noise.

[0003] The existing ball mill liner mainly includes a liner body, a rubber pad, mounting holes, and mounting bolts. In use, the rubber pad is placed between the liner body and the casing, and then the mounting bolts are used to fit and install the rubber pad, the liner body, and the mounting holes on the casing.

[0004] However, in actual use, the liner and the rubber pad are prone to detachment during installation and disassembly. Therefore, the liner needs to be supported and lifted during disassembly or installation to prevent it from falling. At the same time, when the liner and the rubber pad are in contact, they are very easy to be misaligned due to slight vibration, which will affect the overall installation. Utility Model Content
