Alumina Grinding Media Balls
Description
Technical Parameters
Products Description
Alumina grinding media balls are divided into three grades based on alumina content: medium alumina balls (60% -65%), medium high alumina balls (75% -80%), and high alumina balls (90% -99%). Among them, high aluminum balls are divided into 90%, 92%, 95%, and 99%. 99% of production costs are high and are mostly used for special occasions.
High alumina balls are made of high-quality alumina raw materials. After high-temperature sintering, the internal structure is dense and uniform, with high packing density and moderate hardness, which can increase the effective volume of the ball mill and shorten the grinding time. At the same time, they have high whiteness and do not contaminate grinding materials, making them particularly suitable for fields such as white cement, ceramic glazes, minerals, etc. that require high purity.
Advantages
1. High hardness and low wear
The Mohs hardness is as high as 9, second only to diamond, and the Rockwell hardness is HRA80-90, far exceeding wear-resistant steel. The wear loss is controlled below 0.01%, and the wear resistance is more than 10 times that of steel grinding media and 266 times that of manganese steel, greatly reducing the consumption and replacement cost of grinding media.
2. High whiteness, pollution-free
This product is white and clean, without adding dyes. It does not introduce metal impurities or colored pollutants during the grinding process, fully ensuring the whiteness and purity of grinding materials such as ceramics and coatings.
3. High packing density and high grinding efficiency
Adopting the isostatic pressing and rolling forming process, the bulk density reaches 3.65-3.68g/cm ³, enhancing the impact force during the grinding process. Compared with natural pebbles, the grinding efficiency is increased by 20% -40%, and the bearing capacity of the material is improved.
4. High temperature resistance and corrosion resistance
It can withstand high temperatures above 1000 ℃, has strong corrosion resistance to acids, alkalis, and organic solvents, does not react with grinding media, and is suitable for various harsh grinding environments.
5. Low water absorption and stable performance
The water absorption rate is less than 0.01%, and there is no moisture absorption or powdering phenomenon. The performance remains stable during long-term wet grinding operations and will not affect the quality of powder products.
6. Good roundness and smooth surface
The surface is smooth and has high roundness, reducing wear on the inner walls and pipes of the ball mill, avoiding material accumulation, and improving the smoothness of the grinding process.
Application
1. Architectural ceramics industry
Used for grinding ceramic blanks, glazes, and ceramic pigments, improving the fineness and uniformity of powders, ensuring the whiteness and quality of ceramic products.
2. Coatings and pigments industry
Suitable for grinding water-based coatings, oil-based coatings, titanium dioxide, and inorganic pigments to avoid metal contamination and maintain the color purity of coatings.
3. Electronic and Magnetic Materials
Suitable for grinding electronic ceramics, semiconductor materials, magnetic materials, and lithium battery raw materials, meeting the high purity requirements of electronic materials.
4. Mineral and chemical powders
Suitable for grinding non-metallic minerals such as kaolin, talc, quartz powder, as well as various chemical raw materials, with high grinding efficiency and low loss.
5. Medicines and food powders (non-medical grade)
Used for grinding food additives and raw materials with low purity requirements, providing clean and pollution-free grinding media.
