Flint Pebbles
Product Benefits
French flint pebbles: grind more with less.
- Superior performance as a grinding media compared to any other natural pebble, because of higher hardness, and higher resistance to abrasion
- Low pebbles consumption: 4.5kg of our pebbles are needed to grind 1000kg of white ceramic body (compared to between 7kg-20kg with other pebbles)
- No pollution of the grinded material : >98.5% SiO2 content
- Controlled size and shape
- 8 different sizes adapted to any kind of ball mill.
