Preface
Since we are a professional ceramic inert ball factory with many years of experience, our products are of higher quality and the prices are more favorable. Of course, having the conditions to produce ceramic inert balls is not enough. The most important thing is that we want to excel in the production of ceramic inert balls, especially in sales and after-sales services. Doing one thing is easy, but doing it well requires a lot of time and effort. This is exactly what we do.

Core properties
In harsh working conditions such as those in petrochemical and coal chemical industries (high temperature, high pressure, strong acid/alkali environment), it does not react chemically with the oil and gas, catalysts, acid and alkali solutions in the reaction system, nor does it release impurities. At the same time, it possesses physical properties such as high temperature resistance, corrosion resistance, and high strength, and can stably maintain its structural form.

Main applications
Ceramic inert balls are mainly used in tower equipment such as reaction towers, absorption towers, and desulfurization towers. They primarily serve three functions – supporting the catalyst (preventing the catalyst from being crushed due to gravity and ensuring the porosity of the bed layer), evenly distributing the gas and liquid media (improving the efficiency of medium contact and enhancing the reaction or separation effect), and protecting the components inside the tower (buffering the erosion and wear of the high-speed medium on the tower wall and distributors).

Common Specifications
The diameters of ceramic inert balls typically range from 3mm to 50mm. Common specifications include 1-2mm, 3mm, 6mm, 8mm, 10mm, 13mm, 15mm, 19mm, 25mm, 40mm, and 50mm. The appropriate size can be selected based on the diameter of the tower, the flow rate of the medium, and the size of the catalyst particles. Moreover, as the diameter increases, the compressive strength also increases (for example, the compressive strength of 3mm balls is ≥ 28kg per particle, and that of 75mm balls is ≥ 10000kg per particle).
