Low Breakage Intermediate Diaphragm / Retention Ring Liners Cement Mill 

Specification                                                               

1. Material:High Cr Cast Iron

2. Hardness:≥HRC52

3. Impact Value:More than AK10J

4. Application:Mining Industry

5. MOQ:2tons

High Cr white iron material possess a combination of superior abrasion resistance and a reasonable 

degree of toughness. The high Cr castings have longer service life than the other material,such as 

high Mn steel and Cr-Mo alloy steel.And now it is widely used in the working condition of high wear and  low impact,such as dry grinding process,coal mills,cement mills due to its excellent performance.
