Alumina Packing Ball

Alumina Packing Ball

Alumina packing balls are small, high-purity ceramic balls that are widely used as packing material in towers, columns, and reactors in the chemical, petrochemical, and oil and gas industries. They are typically made from high-grade alumina powder that is sintered at high temperatures to form a dense, hard, and wear-resistant ceramic material.

The main function of alumina packing balls is to provide a large surface area for gas or liquid contact while also providing good mechanical stability and resistance to chemical attack. They are commonly used in applications such as absorption, distillation, and filtration, where the contact between the fluid and the packing material is critical to achieving the desired separation or reaction.

Alumina packing balls are available in a range of sizes, typically ranging from 3mm to 50mm in diameter. They are also available in different shapes, such as spherical, cylindrical, and trilobed, to suit different types of packing applications.

One of the key advantages of alumina packing balls is their high mechanical strength and resistance to abrasion, which makes them a reliable and long-lasting packing material. They are also highly resistant to thermal shock and can withstand exposure to high temperatures without cracking or degrading.

Alumina packing balls are inert and chemically stable, which ensures that they do not react with the fluids they come into contact with. This makes them suitable for use in a wide range of corrosive and high-temperature environments.

Overall, alumina packing balls are a highly effective and versatile packing material that can be used in a wide range of applications. Their superior mechanical properties, chemical stability, and resistance to abrasion and thermal shock make them a popular choice for use in the chemical and petrochemical industries.

Alumina Packing Ball Features

Alumina Packing Ball can withstand the corrosion of acid, alkali and other organic solvents, and the temperature change in the production process. As the support and cover material of the reactor, it can buffer the influence of liquid and gas into the reactor on the catalyst and protect the catalyst. Many Alumina Ceramic Inert Packing Balls exhibit much greater hardness than steel balls, resulting in longer life and improved reliability.

Alumina Packing Ball Applications

Alumina Packing Ball is widely used in petroleum, chemical industry fertilizer, natural gas, environmental protection, and other fields, as the catalyst in the reactor cover support materials and tower filler. The main effect is to increase the distribution of gas or liquid, to support and protect low-strength active catalysts.



We handle our products with care to ensure they remain in their original condition during storage and transportation and to preserve their quality.
