The other is to separate the end cap and the hollow shaft for processing, and finally assemble the two castings. You can use bolts to connect, but the effect is that the material consumed is relatively large and the processing volume is relatively large. When the ball mill is running, it is necessary to bring up the grinding body. After throwing it out, the crushed material is mixed into the material. When the grinding body is lifted up, it will slide along the inner wall of the ball mill barrel and will directly face the barrel The inside causes more serious wear and tear, so a liner is added. This is mainly to protect the inner wall of the cylinder and the grinding head from the impact of the grinding body and the grinding of the material.

The surface of the liner can be processed into many different shapes, so the ball mill liner will also help improve the grinding body, improve the grinding effect, and improve work efficiency.
