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.
