High Thermal Conductivity 20 W/mK Alumina Ceramic Grinding Balls with Low Wear Rate and Low Water Absorption for Efficient Grinding
Product Description:
High hardness alumina grinding balls are core grinding consumables in ceramic, mineral, and cement industries, known for their compatibility with hard materials. They effectively address the low efficiency and wear issues faced by ordinary grinding balls when dealing with materials like quartz sand and corundum. After a ceramic company used them for glaze grinding, production efficiency increased by 20%, defective product rate decreased by 15%, ensuring production stability and product quality.
Features:
The grinding balls have a Mohs hardness of over 9, second only to diamond. They are produced using high-temperature sintering process, resulting in a smooth and dense surface (surface roughness Ra0.8μm or less). Third-party tests revealed a wear rate of only 0.3% when continuously grinding quartz sand, significantly lower than the 1.5% wear rate of regular grinding balls, with minimal debris generation to avoid material contamination.

Applications:
In ceramic glaze grinding, the grinding balls maintain a fineness of 325 mesh screen residue ≤0.1% and reduce grinding time by 1.5 hours. In the corundum grinding in the mineral industry, they help maintain efficient grinding, increasing fine powder yield by 25%, ensuring uniform particle size to meet processing needs in various high-hardness material grinding scenarios.
Support and Services:
Pre-sale services include professional selection based on material hardness and equipment parameters. During the sale, technical personnel guide installation and placement. Post-sale services involve regular follow-ups, quarterly wear tests, and timely reminders for ball replacement to ensure continuous and stable grinding processes.
Addressing customer worries about wear resistance, the product provides actual test data (e.g., grinding quartz sand for 8-10 months). For purity concerns, a debris content test report of ≤0.01% is offered. Concerning equipment compatibility, an adaptation comparison table with mainstream equipment is provided to eliminate customer doubts.
