| Forged Grinding Steel Balls | Medium- to high-carbon alloy steel, commonly heat-treated after forging | 20–150 mm | Approximately 55–65 HRC, depending on grade and heat treatment | Approximately 7.80–7.85 g/cm³ | Large ball mills used in copper, gold, iron ore, limestone, cement and other mineral-processing operations | $650–$1,200 | Asia, Europe, South America and other major steel-producing regions | Check chemical composition, impact toughness, surface hardness, volumetric hardness, roundness and breakage rate |
| Low-Chromium Cast Grinding Balls | Cast alloy iron or steel with a relatively low chromium addition | 20–150 mm | Approximately 50–62 HRC | Approximately 7.30–7.80 g/cm³ | Cement grinding, limestone processing and mineral applications with moderate abrasion | $600–$1,050 | Asia, Europe, the Middle East and regional foundry markets | Review chromium content, carbide distribution, microstructure, wear test results and casting-defect controls |
| High-Chromium Cast Grinding Balls | High-chromium white cast iron or alloyed cast iron | 20–130 mm | Approximately 58–68 HRC | Approximately 7.40–7.80 g/cm³ | High-abrasion cement, mining, power-generation and mineral-processing mills | $900–$1,800 | Asia, Europe, North America and other established foundry regions | Request chromium percentage, matrix structure, carbide morphology, hardness profile and dimensional inspection records |
| High-Chromium Alloy Steel Balls | Alloy steel containing chromium and other controlled alloying elements | 25–120 mm | Approximately 58–66 HRC | Approximately 7.70–7.85 g/cm³ | Fine grinding and high-wear applications where impact resistance and abrasion resistance are both required | $1,000–$2,000 | Asia, Europe and specialized alloy-steel production regions | Compare chemical certificates, heat-treatment records, fatigue resistance and media consumption in comparable mills |
| Ceramic Grinding Balls | High-alumina ceramic, zirconia-reinforced ceramic or other technical ceramic compositions | 0.5–100 mm | Typically 8–9 Mohs hardness; exact performance depends on composition | Approximately 2.4–6.0 g/cm³, depending on ceramic type | Fine grinding, bead mills, paint, coatings, ceramics, chemicals, pharmaceuticals and contamination-sensitive processes | $1,800–$6,000 | Asia, Europe and North America | Check alumina or zirconia content, bulk density, water absorption, wear loss, size tolerance and contamination limits |
| Stainless Steel Grinding Balls | Martensitic, austenitic or other corrosion-resistant stainless-steel grades | 0.5–100 mm | Approximately 45–62 HRC for hardened martensitic grades; lower for many austenitic grades | Approximately 7.70–8.00 g/cm³ | Food, chemical, pharmaceutical, laboratory and other applications requiring corrosion resistance | $2,000–$5,500 | Asia, Europe and North America | Verify stainless grade, magnetic properties, corrosion resistance, surface finish, sphericity and traceability |
| Grinding Media Cylpebs | Forged steel, cast alloy iron or ceramic materials formed as short cylinders | Typically 10–30 mm diameter and 10–35 mm length | Depends on the selected steel, alloy iron or ceramic grade | Depends on the selected material | Fine grinding and applications where increased contact area is preferred over spherical media | $700–$2,500 | Asia, Europe and other industrial manufacturing regions | Compare material grade, size distribution, wear rate, packing density and compatibility with mill lining |
| Small-Diameter Grinding Balls | Steel, stainless steel, ceramic or zirconia according to process requirements | 0.5–20 mm | Material-dependent; ceramic media commonly measure 8–9 Mohs | Material-dependent | Laboratory mills, stirred mills, bead mills, ultrafine grinding and high-surface-area milling | $1,000–$8,000 | Asia, Europe and North America | Check particle-size distribution, sphericity, surface finish, wear debris, contamination risk and packaging quantity |
