AI Technical Summary
The existing ball mill jar has a height difference between the end cap and the inner wall of the ball mill jar, which makes it impossible for the material to flow smoothly during rotation, resulting in severe wear of the end cap, short service life, and inconvenience in disassembly and assembly.
Multiple cylindrical and conical structures are installed on the end cover of the ball mill jar. The cylindrical structures block, divert, and decelerate the material movement, while the conical structures regulate airflow, preventing the material from directly impacting the end cover and extending its lifespan.
It effectively reduces the scouring and impact of materials on the end cap, reduces the risk of wear, extends the service life of the end cap, improves the ease of disassembly and assembly, and ensures the stability of the grinding process.
