Product introduction:
Flint pebble is a high quality ceramic grinding media for ball mill, can grind ceramic raw materials(feldspar, quartz, Kaolin), cement and glass raw materials. Flint pebbles (silica pebbles) have three different grades: Grade A, Grade B and Grade C.
The main ingredients of flint pebbles are silicate and oxide metals, including silicon, aluminum, sodium, calcium, magnesium, iron, and other elements. These ingredients have a very important impact on the ceramic industry.
First of all, silicon is one of the important components to make ceramics. Flint pebbles are rich in silicon elements and are one of the main raw materials for making porcelain and pottery. Silicon has a strong whitening effect in ceramics, making ceramic products whiter, and it can also increase the hardness and wear resistance of ceramics.
Secondly, aluminum in flint pebbles is a good oxidant that can accelerate the sintering process of ceramics and increase the density and hardness of ceramics. In addition, aluminum can also make ceramics have a good texture and gloss.
In addition, sodium and calcium in flint pebbles have a great impact on the quality and appearance of ceramics. Sodium is an important additive that can improve the transparency and brightness of ceramics and make them more crystal clear. Calcium can improve the toughness and plasticity of the ceramics and make it more tough.
Finally, magnesium and iron in flint pebbles a good diluents that can weaken the color in the ceramics and make the ceramics show a softer tone. The iron can increase the color depth in the ceramics, making the ceramic more stylish.
Technical indicator:
SiO2 | ≥99.31% | Volume density | ≥2.66g/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 condition, test report from our Japanese customer show the difference from our Dalian pebbles & French pebbles:
Density: 2.68g/cm3 of Dalian pebbles higher than 2.62g/cm3 of french pebbles.
Wear loss: wear loss of Dalian pebbles is 40g, less than 50g of french pebbles.
Our advantages and services:
Dalian Gaoteng was established in 2000, has rich export experience, cooperate with over 170 customers, often export to Japan, Southeast Asia, Europe, the middle east…
Due to customers from different industries could have different requirement, we can help you to choose suitable product.
Besides, we have own logistics company, can offer the best service and favorable price to you.
Packing details:
Jumbo Bags
One Bag With One Pallet
Two Bags With Pallet
In Bulk
Production process:
Gaoteng flint pebbles are from the mine, not from the river or the sea.
First, we mine silicon ore from the mountains. Then, sorting the silica raw rock, process the preform pebbles. Next, we put the pebbles into a ball mil, after grinding 6-8 hours into the ball mill, the rocks become round. And we will screen different sizes by machine and hand. Finally, we pack the flint pebbles into bags.
