Stainless Steel Grinding Media

Basic Information

Specifications

Product Description：

Stainless steel grinding media is a popular choice for grinding applications where contamination from the grinding media is not desirable. Stainless steel spheres are best suited for grinding high-strength, low-viscosity materials such as ores, ceramics, and minerals.

Material Variety: Available in different stainless steel grades, including 304, 316, 420, and 440, offering choices based on specific application requirements.

Applications: Precision metal components, bearings, household appliance bearings, automotive components, hydropower generation, precision mechanical components, ball screws, medical instruments, seawater equipment, food grinding, body jewelry, valves, chemical industry, decoration, aerospace, and other industries.
