Number and Size of the Balls
1. Pregrinding the coarse, hard material with large balls
2. Use of many small balls will increase the fine fraction if the running time is increased
3. A higher mass (spec. weight) of the grinding balls will accelerate the grinding
4. 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 | 10 mm |
Homogenisation of viscous samples | 20 mm |
These are just clues: the size of grinding jars and grinding balls should be determined experimentally if necessary.
Choice of Grinding Jars & 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.
