What Material Is the Liner of Ball Mill Machine Made of?

The liner of ball mill machine is impacted and grinded by grinding medium and raw materials, so that it is easy to be worn and shortened its service life. This article will give you a specific introduction of materials used for making the liner of ball mill machine to make users have a correct selection. The following is the analysis:

1. High manganese steel liner: high manganese steel is a wear-resistant material with a long history. It is the most general materials used in ball mill machine. It has a good of strength and toughness. It can be hardened in big impact load. After processing, the hardness of its surface can be improved from HB170~225 to HB500~800. It is suitable for using in the machine with strongly impact load.

2. Chromium white cast iron liner: chromium white cast iron liner has a high hardness but poor wear-resistance and toughness. Its stress concentration is sensitive, so it is generally used in medium and large scale ball mill machine. For large scale ball mill machine, the liner must be small and thick, and must be installed carefully. Chromium white cast iron liner is easy to break and crack. For the complicated and thin-walled large liners such as end plate, grate plate, you’d better do not use chromium white cast iron liner.

3. Rubber liner: rubber liner is made of wear resistant rubber. Its thickness is 50mm, which is thinner than stone liner. Besides, rubber is very light, so the weight of the robber liner is one-sixth of stone liner’s. If they are used in the same size ball mill machine, the equipment with robber liner can save 10-20% effective room. And its power consumption is greatly reduced.

4. High chromium cast iron liner: the impact toughness of the high chromium cast iron liner is low, and dose not impact. It is only used for conditions requiring small shocks. This material has been used to make corrugated liners and ladder liner with 10 years service life.
