Description

Technical Field

[0002] White corundum is a synthetic material with high hardness and high density, mainly used in abrasives, grinding, polishing and refractory materials. The production process of white corundum mainly includes: Raw material preparation: Select high-purity alumina as the raw material, usually industrial-grade alumina powder. Melting: Place the alumina raw material into an electric arc furnace or a resistance furnace and melt it at high temperature. By adding appropriate amounts of additives and ores, the composition and properties of the material can be adjusted. Crystallization: After the molten material cools, it will form crystals, namely white corundum. Crushing: The crystals are mechanically crushed to obtain white corundum particles of the required particle size. Grinding: Use a ball mill to crush the raw materials. Screening: The ground raw materials are screened to obtain the required fine-grained raw materials.

[0003] During the actual production process, the crushed raw materials are transported by an elevator to silo one for storage. The raw materials discharged from the silo are then transported by conveying equipment to a ball mill for grinding. The ground materials are then stored in silo two.

The screened finished products are then transported by an elevator to silo three for storage.
