Ceramic Raschig Ring Tower Packing: Properties, Specifications and Industrial Applications

图片
Ceramic Raschig rings are produced from high-alumina, low-iron clay combined with feldspar, quartz, and forming additives through a series of processes including ball milling, iron removal, vacuum pugging, molding, drying, and high-temperature firing. Key chemical indicators: acid resistance ≥ 99.6%, alkali resistance ≥ 85%, maximum operating temperature 1000°C, Mohs hardness > 6.5, water absorption < 0.5%. The material resists corrosion from various inorganic acids, organic acids, and organic solvents, with the exception of hydrofluoric acid. Ceramic Raschig rings are employed across multiple industries: Chemical processing: drying columns, absorption columns, scrubbing towers, and regenerating towers in chemical, metallurgical, coal gas, and oxygen production industries. Environmental engineering: desulfurization, denitrification, and volatile organic compound treatment systems, as well as wastewater treatment towers. Catalyst support: ceramic Raschig rings serve as covering an...

Alumina Ceramics in Steel Plant Material Handling Equipment

图片
Steel production involves a complete process flow, including sintering, ironmaking, steelmaking, and other stages. The high-speed conveying and transfer of solid materials such as iron ore, coke, coal powder, and steel slag are core parts of production operations. Chutes, hoppers, conveying pipes, mixing equipment, and other material handling equipment are constantly exposed to abrasive material erosion, friction wear, material adhesion, and clogging. Traditional carbon steel and wear-resistant steel equipment has a short service life, requires frequent maintenance, and causes high downtime losses, which seriously restricts continuous and efficient steel plant production. High-purity alumina ceramics, with their ultra-high wear resistance, very low friction coefficient, impact resistance, and corrosion resistance, have become a core material for upgrading wear protection in steel plant material handling equipment. They are widely used to retrofit liners in various conveying systems, si...

Impact Resistance of Ceramic Rubber Vulcanized Plates: An In-Depth Analysis

图片
Ceramic rubber vulcanized plates, also known as ceramic rubber composite liners, are composite wear- and impact-resistant materials. By combining the high hardness of ceramics with the high elasticity of rubber, they deliver outstanding impact resistance and are widely used in material handling and impact-buffering applications in mining, metallurgy, ports, building materials, and other industries. Their impact resistance is not simply the sum of the properties of individual materials. Instead, it is achieved through scientific structural design and vulcanization technology, creating a synergistic effect of hard-surface protection and soft cushioning. This helps resist damage from material impacts and equipment vibration, extending equipment service life. 1. Core Advantages in Impact Resistance The impact resistance of ceramic rubber vulcanized plates comes from the complementary properties of ceramic and rubber, combined with an integrated vulcanization process. This creates comprehen...

Low Alumina Ceramic Packing Balls: Properties and Application Guide

图片
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...

Alumina Wear-Resistant Ceramic Liners Solve Powder Conveying Wear Problems

图片
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...

What Is Alumina Ceramic and Why Is It the Preferred Wear-Resistant Material for Industry?

图片
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...

What are the key properties and uses of honeycomb ceramic

图片
Honeycomb ceramic is a porous industrial ceramic material characterized by a regular honeycomb structure of parallel channels. Its internal structure consists of thin grid walls that divide the material into numerous interconnected cell channels, with common cell shapes including square, triangular, and hexagonal. Compared to conventional bulk ceramics, honeycomb ceramic exhibits high specific surface area, low coefficient of thermal expansion, excellent thermal shock resistance, superior chemical stability, strong corrosion resistance, and light weight. The through-channel structure allows for low pressure drop during fluid flow, while also providing good thermal insulation properties and high mechanical strength. Common material compositions include cordierite, silicon carbide, mullite, alumina, and aluminum titanate. Leveraging its structural properties, honeycomb ceramic has found extensive applications across multiple industrial sectors. In environmental protection, honeycomb cera...
