Introduction white corundum: The raw material of white corundum is AL2O3. The production process is that after the alumina is smelted into a block in a high temperature furnace by a high temperature, it is broken into small pieces by a jaw crusher, and then crushed by a ball mill for secondary crushing, magnetically removed and then sieved into various models. The micropowder needs to be pickled and removed. White corundum has high purity, good self-sharpness, low calorific value, strong grinding ability, and good corrosion resistance. It has higher hardness than brown corundum, but it has no toughness of brown corundum. White corundum characteristics: 1. High alumina content and high hardness 2. self-sharpening, acid and alkali corrosion resistance 3. high temperature resistance, stable thermal performance, 4. Strong grinding ability, low heat generation and high efficiency.

1. Introduction: Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well. Because Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage. 2. Deep Processed BFA Calcined BFA: Heating to 1050°C greatly improves the purity, toughness, strength, and wear-resistance of abrasives. Primary application: vitrified grinding wheels. Blue-Fired BFA: While turning grain-color dark blue, firing at 1350°C achieves far greater toughness and strength, much lower iron content, a very low coefficient of thermal expansion, and excellent hydrophilicity, all of which increase grinding performance and accuracy. Primary applications: coated abrasives (paper, cloth and belts) and heavy-duty grinding wheels. Ceramic-Coated BFA: Ceramic coating improves purity and hydrophilicity, reduces dust, and achieves grain surfaces that have greater toughness, strength, and roughness, and that are also more uniform in particle size. Primary applications: coated and bonded abrasives. Ceramic-Coated Blue-Fired BFA: These grains deliver all of the advantages of both Ceramic-Coated and Blue-Fired BFA. Primary application: coated and bonded abrasives, especially for use on hardened steel and other high-carbide materials. 3. Standard Grain Size Abrasive: F12 to F220; P12 to P220; #240 to #1500 Refractory (mm): 0-0.5, 0-1, 1-3, 3-5, 5-8, 0-10, 0-25, 0-30 Refractory (Mesh): -100, -200, -325 4.
