Zirconia grinding media show high crushing strength and fracture durability, leading to higher wear resistance, superior grinding efficiency and longer working life. Moreover, these grinding media are resistant to rust and corrosion, so it will not take pollution to the materials which are ground or dispersed. Nowadays, Zirconia grinding media have been widely applied in fine grinding plants as abrasive media for ceramic raw materials and glaze materials in ceramic, cement, glass, porcelain enamel, paints, pigments, chemicals, pharmaceuticals, paint industry, inks, cosmetics, inorganic mineral powders, fine chemical, coal-chemical, fertilizer, natural gas and environmental protection industries etc. Among various grinding media, Zirconia grinding media is a perfect choice which will help users improve product quality and effeciency.

3 . Advantages of 65 zirconium silicate beads
1. Environmental Protection Characteristics Key Statement
Zero harmful substance emissions: Zirconium silicate beads do not emit pollutants such as heavy metals, volatile organics (VOCs) during use, thus meeting environmental protection production minimum requirements.
Spot-free pollution: Differentiated from the wear and tear problem of traditional grinding media, the high-density structure avoids material and environmental secondary pollution and meets the requirements of environmental protection system certification such as ISO 14001.
2. Industrial Applications and Values
Metal processing
Gold/copper ore grinding: 65 silicate zirconium beads (diameter about 0.65mm, or ZrSiO4 content of 65%) with high hardness (Mohs hardness 7.5-8) and wear resistance, realize precision crushing of ore in the mixing grinding process while eliminating the residue of the grinding medium interference with precious metals purification and help environmental protection fluorescent indicators (e.g. reduction in the use of cyanide + 30%+).
Paint/Ink Production
Nano-grade dispersion process: high polishing efficiency of spherical beads makes the pigment particles 1 μ can be divided into m or less, and the risk of metal ion leakage (e.g. Fe ² It is free from paint discoloration due to It It It ensures the safety standards (FDA 21 CFR 175.300 compliance) for food contact grade paints (e.g. can inner wall coatings).
Environmental compliance benefits: Avoid silicone dust pollution due to conventional glass bead grinding (60% reduction in fine dust PM2.5) and help companies pass the emission limits of the 'Coatings, Inks and Adhesives Industry Air Pollutant Emission Standard' (GB 37824-2019).
3. Sustainable development technology advantage
Counter-dimensional silicate zirconium beads Traditional grinding media (steel beads/glass beads)
Wear resistance Wear rate <0.01%/100h Steel bead wear rate 0.5-1%/100h, glass bead wear rate 0.2-0.5%/100h
Energy efficiency Reduce energy consumption by 15-20% at equal grinding efficiency High hardness materials require higher rotational speed and energy consumption is relatively high
Recycling Rate 5000+ Hours Reusable Steel Beads are easy to dispose of melt sludge and glass beads are high crushing rate
4. Conform to industry prevalence and standards
Policy Contact: Compliance with the "industrial waste reduction" requirements of the "14.5" Circular Economy Development Plan and the safety norms for lubricating media of the European Union REACH regulation (chemical registration, evaluation, waterproofing).
Enterprise Green Transition Tools: As a typical example of "production process environmental protection upgrade" in the ESG (Environment, Society, Governance) report, it can improve the competitiveness of brands in green industries such as new energy automotive battery materials (such as infrared lithium polishing), solar silicon chip cutting.
