92% Alumina Ball
The 92% alumina ball from Zhonglong Materials Group Co., Ltd. is a ceramic grinding medium composed of 92% aluminum oxide (Al2O3), with a Fe2O3 content capped at 0.2%. It achieves a Mohs hardness of 9 and a bulk density of 3.63 g/cm³, delivering high wear resistance for extended service life in abrasive milling environments. The material’s water absorption is a minimal 0.01%, and its crush strength exceeds 2000 MPa, ensuring structural integrity under heavy loads.
This grinding media is engineered for superfine dispersion and grinding in ball mills, pearl mills, and sand mills, commonly used to process minerals like zircon sand, silicon dioxide, and calcite, as well as specialty coatings, paints, and ceramic glazes. The balls maintain a high degree of purity, reducing contamination in end products, and their smooth, shiny surface with excellent roundness minimizes friction and energy loss during operation. Standard industry practice for 92% alumina balls includes typical surface roughness below 0.5 µm and a typical sphericity tolerance of ±0.1 mm.
Primary buyers include mining companies, paint and coating manufacturers, and ceramic producers requiring ultrafine particle size reduction. The product is traded as an industrial consumable with global demand, particularly in sectors where contamination control and grinding efficiency are critical. Sourcing terms such as MOQ, incoterms, and lead times should be confirmed directly with Zhonglong Materials Group Co., Ltd., as these are not specified in the available data.

Sourcing 92% Alumina Ball from Zhonglong Materials Group Co., Ltd. - China Import Guide
Before placing an order with Zhonglong Materials Group Co., Ltd., verify the exact Al2O3 and Fe2O3 content through third-party testing if your application demands stringent purity. Confirm the batch-to-batch consistency of the crush strength and bulk density, as variations can impact milling performance and product quality. Request samples for trials in your specific equipment to assess wear rates and contamination levels.
Clarify logistics details such as packaging standards, which typically include 25 kg or 1-ton bags for bulk shipments, and confirm whether the supplier provides palletized or containerized options. Discuss lead times, which can vary based on order volume and production schedules, and agree on Incoterms such as FOB or CIF to define responsibilities for freight and insurance. Payment terms should also be negotiated upfront, with common options including TT or LC.
For quality checks, inspect the surface finish and sphericity of a sample batch using calipers or a profilometer to ensure they meet the typical tolerances. Request certificates of analysis for each shipment to confirm compliance with the stated specifications. Document the milling efficiency and wear rates during trial runs to establish a baseline for future orders and to address any discrepancies with the supplier.
