Briefing Manufacturing of Alumina Oxide Granulate Powder For ball milling, use a ball mill for high-speed ball milling. Stir until spray granulation is complete. Spray granulation, pressurize the slurry to 200Mpa, dry the 4.slurry at high temperature to form spherical granulated powder Screening, 60-250mesh is qualified. Mixing, so that the product performance is more uniform. Place it and let it stand for 24 hours to make the moisture more uniform and the performance more stable. Sintering temperature: Room temperature:25-30ºC→2h, 300ºC→3h, 600ºC →2.5h, 1000ºC→3h, 1300ºC→3h, 1630ºC→cool down
