Steel balls are categorized into grinding, forged, and cast steel balls based on production technology. Materials range from bearing steel and stainless steel to carbon steel and alloy balls. These components are vital for crushing industrial mining and cement industries.

1. Wire drawing: Stretch wire to desired diameter.
2. Cold heading: Forge into ball blanks using steel dies.
3. Lightball: Remove outer rings and poles.
4. Heat treatment: Carburizing, quenching, and tempering for hardness.
5. Hard grinding: Remove oxide layer and correct accuracy.
6. Precision polishing: Achieve final smoothness and shine.
7. Inspection: Visual and micrometer testing for roundness.
