We’d like to help select suitable material grade for your Grinding Mill Liners as per your specific working condition.
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.
