In the fields of modern ultrafine grinding, material homogenization, and industrial powder production, alumina ceramic grinding balls play a crucial role as the core grinding medium. With its excellent characteristics of low wear, high hardness, impact resistance, and energy saving and environmental protection, it is widely applicable to various harsh grinding conditions. As a professional manufacturer in the industry, HUAO is committed to providing high-quality alumina ceramic series products to global customers.
Core physical properties and microstructure
The excellent performance of alumina ceramic grinding balls comes from their rigorous physical indicators and stable crystal structure:
Extremely high hardness: The Mohs hardness of the grinding ball reaches level 9, which can easily cope with long-term high-speed impact and friction of various high hardness ores and raw materials.
Dense bulk density: The high-density crystal arrangement effectively reduces internal micro pores, thereby significantly improving impact strength and crushing efficiency.
Zero pollution and ultra-low wear: The extremely low wear rate (≤ 0.01%) and water absorption rate (≤ 0.01%) ensure that the material will not introduce impurities during the grinding process, ensuring the high purity of the end product.
Technical parameters and brand classification: AH-92 and AH-95
In order to adapt to the grinding intensity and equipment requirements under different working conditions, high aluminum grinding balls are usually divided into two mainstream technical grades:
AH-92 standard wear-resistant series:
Aluminum oxide content: ≥ 92%
Bulk density: ≥ 3.65 g/cm ³
Hardness and wear: Mohs hardness 9, wear loss ≤ 0.01%, water absorption ≤ 0.01%
Appearance color: White
AH-95 High Purity Ultra Dense Series:
Aluminum oxide content: ≥ 95%
Bulk density: ≥ 3.68 g/cm ³
Hardness and wear: Mohs hardness 9, wear loss ≤ 0.01%, water absorption ≤ 0.01%
Appearance color: White
Classification of Forming Process and Dimensional Specifications
According to different grinding equipment and crushing accuracy requirements, the forming process and size range of ceramic grinding balls exhibit extremely high flexibility:
Rolling: The size range is usually between 0.5 mm<Φ<50 mm, suitable for fine powder grinding.
Pressing: The size range is between 13 ≤Φ ≤ 90 mm, suitable for the main heavy-duty grinding of large ball mills.
Personalized customization: All regular sizes and special specifications can be flexibly adjusted and customized according to the specific working conditions of customers.
Cross industry application areas and HUAO quality assurance
Due to its excellent wear resistance and impact resistance, alumina ceramic balls are widely used in various grinding equipment, including stirred mills, intermittent mills, and continuous ball mills. They have demonstrated excellent production efficiency in the fields of ceramic raw materials, ultrafine grinding of ores, chemical fillers, and fine grinding of cement clinker. During the production and manufacturing process, HUAO implements a strict quality control system, with precise monitoring of raw material ratios and high-temperature sintering to ensure that each batch of products has excellent mechanical strength and wear resistance. Through continuous technological innovation and stable overseas supply, HUAO has won the widespread trust of global partners. High alumina ceramic grinding balls have become an indispensable and efficient medium for modern industrial ultrafine grinding due to their high-purity alumina composition (≥ 92% to ≥ 95%), excellent density (≥ 3.65 g/cm ³), and extremely low wear rate.
