Product introduction:
Flint pebble is a high quality ceramic grinding media for ball mill, can grind raw materials such as ceramic raw materials(feldspar, quartz, Kaolin), cement, and glass raw materials. The pebbles(silica pebbles) have three different grades divided by roundness: Grade A, Grade B, and Grade C.
Technical indicator:
SiO2 | ≥99.31% | Volume density | ≥2.66~2.68g/cm3 |
Al2O3 | ≤0.36% | Hardness | Around 8 Mohs |
Fe2O3 | ≤0.018% | Porosity | ≤0.38% |
CaO | 0.09% | Actual abrasion rate | ≤1.35 |
MgO | 0.04% | Color | Grey and White |
Product features:
High SiO2 with low Fe2O3 contents
High density and hardness and low abrasion
Good roundness
Consistent specification
Comparison report:
Under the same test conditions, the test report from our Japanese customer shows the difference between our Dalian pebbles & French pebbles:
Density: 2.68g/cm3 of Dalian pebbles, higher than 2.62g/cm3 of french pebbles.
Wear loss: the wear loss of Dalian pebbles is 40g, less than 50g of french pebbles.

Tips--How to choose excellent flint pebbles?
Choosing suitable flint pebbles is necessary for the ceramic industry. When select it, need to pay attention to the following tips:
Hardness influence: The higher the silica content of the pebbles, the longer the service life, won't easily wear in the production process. Meanwhile, the higher the hardness, the more delicate the material ground out, and the better the quality.
The sizes: In general, the smaller the size of flint pebbles, the more delicate the material grinding out. However, the size of the stone should also be flexibly determined according to the specific situation, and can not be generalized.
The purity influence: High purity silica can ensure the quality of the material being ground, but also ensure the service life and stability of silica pebbles.
The wear-resistance influence: The wear-resistant silica pellet will not break or break after a long time of use and can maintain a good grinding effect for a long time.
