Custom wear resistance Ball mill liner plate impact crusher lining
The lining plate is used to protect the cylinder body from the direct impact and friction of the grinding body and the material, and the lining plate of different forms can also be used to adjust the movement state of the grinding body to enhance the pulverizing effect of the grinding body on the material. Helps improve the grinding efficiency of the mill, increase production and reduce metal consumption.

The main considerations for selecting various linings are the lifting effect on the grinding medium, the running trajectory of the medium, and the working conditions.
The main lining materials are:
1. medium carbon medium chromium I ZG30Cr5MoRE
2. medium carbon medium chromium II ZG40Cr5MoRE
3. medium carbon low alloy ZG40CrMoNiRE
4. low carbon high alloy ZG20Cr9NiMo
5. chrome molybdenum nickel alloy steel ZG45Cr3NiMoMn-RE
6. 90 chrome alloy steel ZG90Cr6MoM
7. Ordinary high steel ZGMn13
8. modified high manganese steel ZGMn13Cr2
9. super high manganese steel ZGMn17Cr2
10. heat resistant steel ZG20Cr26Ni5
11. HH ZG20Cr26Ni12
12. HK ZG40Cr25Ni20
13. high chromium cast iron KmTBCr15Mo2
14. high chromium cast iron KmTBCr20Mo2
15. high chromium cast iron KmTBCr26
16. high chromium cast steel ZGCr12SiMn-GT
17. high chromium cast steel ZGCr15SiMn-GT
When smashing is dominant, the lining plate is required to have a strong pushing ability for the grinding body, and the lining plate should have good impact resistance. The high manganese steel ZGMn13 has sufficient impact toughness, but is not wearable and easily deformed, and is large. Most have switched to alloy steel or chrome-molybdenum alloy steel liners in the dual-medium quenching process. Comparing several kinds of wear-resistant materials, the alloy steel has the best performance and the longest service life in the double-medium quenching process. The medium carbon low alloy liner produced by Anhui Fengxing is cost-effective, and its wear resistance and toughness are very prominent in the use process.
Precautions and references when purchasing liners
1. The liner is required to have good wear resistance. The high-wear-resistance and impact-resistant double-media quenching of the alloy-shaped steel liner in Anhui has a scientific and rational alloying element formula, which makes the lining board have good physical and chemical properties, the hardness is above HRC45-55, and the impact toughness value is above 25J. The service life is more than twice that of high manganese steel. Can withstand tremendous impact. In the work, the surface shape of the liner can be maintained for a long time to ensure the mill's stability is increased by more than 5%.
2. High strength and high toughness.In the quenching process of the lining, the special double-medium quenching agent with good thermal stability is used as the medium to make the product meet the requirements of high-strength, high-hardness and high toughness to meet the wear-resistant process requirements.
3. High cost performance and adaptability. It is treated by advanced double-medium quenching process. It has the characteristics of high quenching hardness and high toughness value, which makes the lining board have good wear resistance. Compared with high manganese steel lining, medium alloy double The alloy steel ball mill liner in the medium quenching shows excellent cost performance. Can adapt to mine wet grinding, dry grinding, mixed grinding and so on.
