Vertical roller mill is the core equipment of modern grinding system. The grinding roller is the vital grinding component of vertical mill. Because the grinding roller can directly exert force on the material, the grinding roller has high requirements for hardness and wear resistance in actual production.The CHAENG grinding rollers have the characteristics of high hardness, good crack resistance, good abrasion resistance and strong load capacity.

1. CHAENG uses arc gouging to finish the grinding roller and ensure the surface quality.
2. High-quality raw material ZG30mn improvies the hardness and the wear resistance of grinding roller.
3. We provides customized processing service according to the requirements of customers.
4. We inspect the surface stresses through a systematic detection method to ensure the quality of grinding rollers.
5. Our main flaw detection technologies are: ultrasonic flaw detection (UT), magnetic particle flaw detection (MT), and penetrant testing (PT). The whole casting can meet NDT Level III standards, and key positons can reach Level II.
