HUAO high alumina ceramic grinding balls (AH-92 and AH-95) are high-performance ceramic grinding media specifically designed to replace traditional steel grinding media in demanding particle size reduction processes. These media are made of high-purity alumina, with extremely high hardness (Mohs hardness 9), high packing density, and ultra-low wear loss (≤ 0.01%). HUAO ceramic grinding balls are produced through precision rolling and cold isostatic pressing methods, optimizing grinding efficiency while reducing operational energy consumption and preventing slurry pollution in the ceramic, mining, chemical, and cement industries.

Rolling Forming Range: 0.5mm < Φ < 50mm
Pressing Forming Range: 13mm ≤ Φ ≤ 90mm
Custom size distributions can be manufactured according to specific client mill requirements.
High bulk density (≥ 3.65 g/cm³ for AH-92; ≥ 3.68 g/cm³ for AH-95) delivers greater kinetic impact during mill rotations, significantly reducing grinding retention time.
Exceptional hardness (Mohs 9) and a controlled wear loss rate of ≤ 0.01% extend media service life and eliminate color or heavy-metal contamination in ground materials.
Optimized crystalline microstructures prevent media cracking, spalling, or chipping under high-speed impact in continuous industrial mills.
Lower density relative to steel combined with faster milling kinetics cuts overall power consumption, serving as an energy-efficient solution for large-scale operations.
Manufactured via rolling for fine micro-beads (0.5-50mm) and pressing for larger grinding spheres (13-90mm) to match diverse mill configurations.
Ceramic Grinding Balls are designed for high efficiency performance in all standard industrial grinding devices, including agitator mills, intermittent ball mills, and high-capacity continuous mills. Widely used for wet and dry grinding of raw materials minerals, glazes, clays, and inorganic chemicals, such as ceramic body and glaze preparation plants, metal and non-metal mining and beneficiation facilities, chemical and pigment processing industries, cement and building material manufacturing.
HUAO utilizes high-speed rolling granulators and cold isostatic pressing equipment to ensure high sphericity and internal structural density for all diameters. Each production batch must undergo comprehensive physical testing before release, including density, drop impact durability, water absorption, and wear rate. As a direct manufacturer and international B2B exporter, HUAO provides stable bulk supply capabilities, direct pricing, and comprehensive sea freight support.
HUAO delivers customized media gradation ratios tailored to your target material hardness, slurry density, and product fineness specifications. Packaging configurations include 25kg heavy-duty woven bags, 1000kg/1200kg bulk jumbo sacks with inner polyethylene moisture barriers, and reinforced drums fully palletized for ocean transit.
A1: Yes, HUAO operates in full compliance with certified ISO 9001, ISO 14001, and ISO 45001 management systems, enforcing batch-wise quality control on raw materials and finished ceramic media.
A2: AH-92 (≥ 92% Al₂O₃, bulk density ≥ 3.65 g/cm³) provides a versatile, cost-effective solution for general ceramic body and glaze milling. AH-95 (≥ 95% Al₂O₃, bulk density ≥ 3.68 g/cm³) offers higher density and greater resistance to severe abrasion, making it preferred for heavy-duty mining and chemical milling.
A3: Spheres from 0.5mm to 50mm are produced using precision rolling forming, while spheres from 13mm to 90mm are manufactured via cold isostatic pressing to ensure internal density.
A4: Ceramic media have a lower density than steel, reducing the total weight load on mill drives and gearboxes, which significantly lowers electrical power requirements while maintaining rapid grinding rates.
