Zirconium silicate beads are made from imported zircon sand, finely ground and rolled into billets, and formed through sintering phase separation process. It has the characteristics of high compressive strength and low wear, and is widely used for ultrafine grinding of products such as calcium carbonate, kaolin, titanium dioxide, paint, ink, etc.

4.. Wear-resistant performance and key technical indicators
Physical wear resistance data
Wear rate: When grinding titanium percentage pulp in high-speed mixer grinding (3000rpm), the wear rate of 65-silicate zirconium pulp is lower to 0.002%/100h, which is 25 times better than conventional zirconium pulp (0.05%/100h) and 250 times better than aluminum pulp (0.5%/100h).
Hardness and hardness: Non-temperature hardness 1200-1500HV, insulation hardness 5-6MPa·m ¹/², Forming the impact resistance structure of "high-altitude surface + star gas", it is not easy to produce fine cracks in continuous impact grinding.
Wear resistance function analysis
Microstructure advantage: through high-temperature sintering (1650-1750 ℃) to form dense ZrSiO4 crystals, effectively inhibit crystalline gap <100nm, grinding particle cutting depth;
Surface treatment process: Surface roughness Ra<0.1 using atmospheric fluorescence technology μ Reduces frictional resistance and adhesive wear during grinding by m.
5.. Typical industrial scene wear-resistant applications
Paint / Ink Polishing Field
Solvent paint high-speed dispersion: 65 silicon zirconium beads in automotive original paint (OEM) grinding can withstand long-term brush of solvents such as dimethylbenzene, butylester, and after 8000 hours of continuous use, the bead distance change <1%, pigment particle D50 0.5 μ It can be stabilized by m and avoid coating gloss fluctuations due to bead wear (GU<1.5).
5. Optimization of the wear resistance process and loss control
Matching device parameters
Rotation speed control: according to the ball size adjustment, the recommended linear speed for 0.5mm balls is 12 to 15M/s, and 1mm balls are recommended for 8 to 10M/s, so as to avoid impact crushing caused by super speed;
Ball filling rate: Wear resistance scenarios are recommended to be controlled at 55 - 60% (60 - 65% traditionally), which reduces wear from interball collisions.
Management of sludge characteristics
Viscosity threshold: when grinding high viscosity paste (e.g., ink ≥ 5000cp), first dilute below 2000cp, to prevent the heat generated by rubbing the balls from causing local softening wear;
Impurity control: filtered through a 100 mesh sieve before feeding, preventing Fe, sio₂ and other hard particles from mixing to aggravate scratches on the surface of the balls.
