High-strength zirconium silicate composite ceramic grinding medium and preparation method thereof

The invention relates to the technical field of ceramic grinding media, and discloses a high-strength zirconium silicate composite ceramic grinding medium and a preparation method thereof. Comprising the following components in parts by weight: 60-80 parts of low-grade tailing zircon sand, 15-30 parts of treated zirconium-aluminum composite ceramic waste grinding material powder, 0-10 parts of bauxite, 2-8 parts of dolomite, 1-3 parts of barium carbonate, 2-5 parts of yttrium oxide, 2-5 parts of sodium montmorillonite and 1-2 parts of a dispersing agent. The raw materials are low in cost, the preparation method is simple, the prepared high-strength zirconium silicate composite ceramic grinding medium is high in strength and has very high toughness, abrasion resistance, scouring resistance, corrosion resistance and abrasion resistance, and the abrasion of the high-strength zirconium silicate composite ceramic grinding medium is superior to that of conventional zirconium silicate beads; the service life is long
