Product introduction:
Dalian Gaoteng is manufacturer of silex balls(flint pebbles / silica pebbles)
Specific advantages of Gaoteng silex balls / flint pebbles:
High SiO2 content≥99%
Low iron content≤0.02%: Important for applications where iron contamination must be minimized, such as white ceramics and paints.
High density≥2.66g/cm³: Increases grinding efficiency compared to lighter grinding media.
Self-sharpening: The abrasive nature of flint pebbles helps them break against each other during grinding, maintaining their effectiveness over time.
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 |
Application field:
Grinding ceramic raw materials: Flint pebbles are the preferred choice for grinding glazes, bodies, and other ceramic materials due to their low iron content and ability to produce fine, uniform particles.
Grinding minerals for paint and pigments: Flint pebbles are used to grind minerals like limestone, barite, and titanium dioxide into fine powders for paint and pigment production.
Grinding minerals for chemical and pharmaceutical industries: Flint pebbles are used to grind various chemicals and pharmaceuticals into fine powders for different applications.
Pre-grinding for ball mills: In some cases, flint pebbles are used in preliminary grinding stages before the material is processed in ball mills with smaller grinding media.
Product features:
High SiO2 with low Fe2O3 contents
High density and hardness and low abrasion
Good roundness
Consistent specification
silex balls are a valuable tool for grinding minerals thanks to their durability, chemical inertness, and ability to produce high-quality results. Their specific properties make them suitable for a wide range of applications, particularly those where purity and fine particle sizes are important.
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.
