High-Chrome Wear Plates & Liners for Vertical Mills
Product Description
Yile Machinery is a specialized foundry manufacturing ultra-hard, abrasion-resistant wear plates for Vertical Roller Mills (VRMs). Our grinding table liners and segments are engineered to provide maximum service life and operational efficiency in the highly abrasive environments of cement, power, and mineral grinding.
By using premium high-chrome white cast iron, our wear parts offer superior resistance to abrasion, reducing downtime and lowering the total cost of ownership for your grinding operations.
Unmatched Abrasion Resistance with High-Chrome Iron (ASTM A532)
The exceptional performance of our wear plates comes from their material composition. We produce our liners using high-chrome white iron, a class of materials compliant with the ASTM A532 standard.
Microstructure: The material features a high volume of extremely hard chromium carbides (Cr7C3) embedded within a tough martensitic or austenitic matrix.
Extreme Hardness: After a precise multi-stage heat treatment process, our wear plates achieve a hardness of over 60 HRC (650 HBW) .
Superior Wear Life: This combination of hard carbides and a tough matrix provides outstanding resistance to gouging abrasion from materials like cement clinker, coal, and hard rock.
Material Specifications & Grades
We produce wear plates in various grades to match the specific needs of your application.
Material Grade | Chrome Content (Cr %) | Hardness | Typical Application |
Cr15Mo | 14% - 18% | >60 HRC | General purpose for cement raw meal and coal grinding. |
Cr20Mo | 18% - 22% | >61 HRC | Increased wear resistance for more abrasive materials. |
Cr26 | 24% - 28% | >62 HRC | Maximum wear and corrosion resistance for cement and slag. |
