Product Description
Grinding balls are the media for grinding materials in ball mill equipment. The collision and friction between the steel balls of ball mills and materials produce grinding and peeling effects. Important basic components, especially precision industrial steel balls, play a huge role in the development of the national economy. effect. Widely used in cement plants, power plants, etc. High and low chromium multi-element alloy steel balls, high and low chromium multi-element alloy casting and forging.1.Cast grinding ballCasting is a process in which smelted metal liquid is poured into a mold and cooled and solidified to obtain parts with the required shape and properties.According to the different chromium content, cast grinding balls can be divided into high chromium grinding balls, medium chromium grinding balls and low chromium grinding balls.

- medium chromium grinding balls
Medium-chrome steel balls typically refer to steel balls containing chromium in the range of 3% to 10%. According to national standards, medium-chrome balls are required to have a hardness greater than or equal to 47 HRC (Rockwell hardness). To ensure quality, medium-chrome balls undergo high-temperature tempering treatment to eliminate casting stress.This tempering process is crucial for enhancing the performance and reliability of medium-chrome steel balls. By subjecting them to controlled heating and cooling cycles, we eliminate internal stresses, improve hardness, and enhance overall durability. As a result, our medium-chrome steel balls meet or exceed industry standards, making them a dependable choice for a wide range of applications where hardness, quality, and resilience are essential.Technical Parameters Surface hardness | ≥48~55HRC | ≥52~67 HRC |
