Low alumina ceramic packing balls are inert ceramic spheres manufactured from bauxite and kaolin through molding and high-temperature sintering. Their alumina (Al₂O₃) content typically ranges from 17% to 31%. Inert ceramic balls are classified into five grades based on Al₂O₃ content: common ceramic balls, low alumina balls, medium alumina balls, high alumina balls, and corundum balls. Low alumina balls occupy the second grade. Low alumina ceramic packing balls exhibit the following core performance characteristics: Chemical stability. Low alumina balls demonstrate good corrosion resistance to acids, alkalis, and various organic solvents. Acid resistance can reach 98% or higher, while alkali resistance is no less than 85%. In corrosive media environments commonly found in petrochemical and fertilizer production, their chemical properties remain stable. Thermal stability. The maximum heat resistance temperature of low alumina balls reaches 1200°C, with a thermal shock resistance of no le...

In industries such as thermal power, mining, coal, and building materials, powder and granular material conveying systems are subject to severe wear. Coal bunkers, ore silos, ash silos, and conveyor chutes are among the most wear-prone equipment. Raw coal, mineral powder, fly ash, sand, and gravel continuously scour the inner walls of bunkers and chutes at high speed. Combined with gravity impact and friction from the materials, traditional carbon steel and manganese steel liners are highly prone to thinning, perforation, and deformation. Most companies face common pain points. Ordinary steel plate liners have a short service life and require replacement every three to six months. Frequent shutdowns for disassembly and replacement disrupt production schedules, reduce capacity, and incur substantial labor and spare parts costs. In some applications, wear-resistant coatings and polyurethane liners provide short-term wear relief, but they cannot withstand high temperatures, age easily, an...

In industrial settings such as mining, thermal power, chemicals, building materials, and powder conveying, equipment wear, corrosion, and high-temperature degradation are major challenges that disrupt production. These issues shorten equipment service life, cause frequent downtime for repairs, and significantly increase operation and maintenance costs. Alumina ceramic, with its exceptional wear resistance, corrosion resistance, and high-temperature performance, has become a leading choice in industrial wear protection. It is widely replacing traditional steel plates and conventional wear-resistant materials, helping companies reduce costs and improve efficiency. Alumina ceramic is a specialty ceramic material made from alumina (Al₂O₃) as the core raw material through batching, forming, and high-temperature sintering. In the industry, it is commonly classified by alumina purity into three main categories: 92% alumina ceramic, 95% alumina ceramic, and 99% alumina ceramic. Different purit...
