2020-07-31

The usual particle size of brown fused alumina is 4 mesh to 325 mesh. In addition, we also produce products of brown fused alumina powder, brown fused alumina powder, brown fused alumina segment sand and other specifications. For special specifications, we can process and produce according to customer requirements. In addition to mesh number and specifications, brown fused alumina is also divided into grades, including grade 1, grade 2, and grade 3.

Each grade of brown corundum has different uses. Like the secondary brown corundum we introduced today, it is widely used in many industries such as sandblasting, polishing, grinding, anti-corrosion and rust removal, stone carving, and emery cloth materials. The physical and chemical indicators refer to technical indicators such as the physical properties, physical properties, chemical composition, chemical properties, and chemical properties of the product, that is, the quality indicators of the product. To put it bluntly, it is like the "business card" of the product, in order to let everyone know it more clearly. Let's take a look at the physical and chemical indicators of secondary brown corundum.
