Description for 3 mm Agate Milling Media
- Specifications
- Features
- High purity, low contamination to the samples
- High cost-effective, low wear and long lifetime
- High specific gravity, high grinding efficiency
- Highly wear resistant to acid and solvents
- Highly polished, smooth, easy to clean, low abrasion to the equipment
- High mechanical strength, good toughness, impact resistance, no broken beads
- Mainly used for lab planetary ball mill machine
Use of the Milling Media Balls
- Pregrinding the coarse, hard material with large balls
- Use of many small balls will increase the fine fraction if the running time is increased
- A higher mass (spec. weight) of the grinding balls will accelerate the grinding
Size of the Grinding Balls
Type of feed material |
Ball diameter |
Hard samples feed particle size <10 mm |
30 mm or 40 mm |
Medium piece size (<5 mm) |
20 mm |
Fine material (0.5 mm) |
10 mm or 5 mm |
Homogenisation of dry or liquid samples |

These are recommendations: the size of grinding jars and grinding balls should be determined experimentally if necessary.
Choice of Grinding Jars & Grinding Balls
In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen.
