Product Overview

HUAO Alumina Ceramic Grinding Balls (HA-92 and HA-95) are high-density ceramic grinding media engineered for fine and ultra-fine grinding across demanding industrial environments. Manufactured in our facilities, these media are produced using advanced rolling and pressing forming technologies to deliver maximum mechanical durability and precise spherical geometry. Featuring exceptional Mohs hardness (9), low wear loss (≤ 0.01%), and superior impact resistance, HA-92 and HA-95 significantly reduce contamination while optimizing energy efficiency in milling operations. HUAO supplies these high-alumina media directly to global B2B clients in ceramic, mining, chemical, and cement processing sectors.

Technical Specifications

Key Features

• Low Abrasion and Contamination: Ultra-low wear loss (≤ 0.01%) ensures long service life and keeps ground mineral slurry and ceramic bodies pure.
• Extreme Hardness and High Density: Reaching a Mohs hardness of 9 and high bulk density (≥ 3.65 g/cm³ for HA-92; ≥ 3.68 g/cm³ for HA-95), providing rapid crushing efficiency and shorter milling cycles.
• Superior Impact Resistance: High mechanical compaction prevents media cracking, chipping, or deformation under high-stress, continuous grinding loads.
• Energy-Efficient Grinding: High density and uniform spherical shape increase kinetic energy transfer per mill rotation, yielding significant energy savings and operational eco-friendliness.
• Versatile Size Range & Forming Methods: Available in micro-beads and large media options, manufactured via rolling (0.5-50mm) or pressing (13-90mm) processes to fit various mill dimensions.

Applications

Fully suitable for all types of grinding equipment, including stirring mills, batch mills, continuous ball mills, and vertical grinding systems.

Widely used for ultra-fine grinding of raw materials and minerals across the ceramic, mining, chemical, cement, and glaze preparation industries.
