Brown fused alumina AL2O3 for abrasives
White corundum is made from fine alumina oxide powder and crystallized by high temperature electric melting. Its hardness is slightly higher than that of brown corundum with low toughness, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, resistance to acid and alkali corrosion and high temperature thermal stability.
The production process
1. White corundum is crystallized by smelting at high temperature in an arc furnace with high-quality aluminum oxide powder as raw material
2. Use jaw crusher to break crystals
3. Vertical ball mill is used to conduct secondary grinding of the crushed crystals to make them finer
4. Magnetic separation to remove impurities
5. Screening model
6. Weigh and package all models and store them in storage
