1. About Silica pebbles / Flint pebbles
Name: Silica pebblesOther names: Flint pebbles, Silica grinding pebbles, Silica grinding ballsProperty: Round gray-white silica stoneSize: 2-4cm, 4-6cm, 6-8cm, 8-10cm, 10-12cm, 12-15cmApplication: Silica pebbles can be used as grinding medium in ceramics. It is suitable for all kinds of ceramic raw materials.Operational principle: Ceramics factories usually use intermitten ball mill. A proper amount of ceramic raw material silica pebbles and water are put inside the ball mill according to productive requirement. When ball mill starts working, grinding materials will be moving upwards clinging cloely to the inner wall of the ball mill under the effect of centrifugal force. When the grinding materials reach a certain height, they will drop with a certain speed with the effect of gravitation. During this procedure, ceramic raw material will be ground because of the crushing and grinding movements. Chemical composition and physical properties:| SiO2 | >=99.31% |
| Al2O3 | <=0.36% |
