Product Details
Alumina ceramic ball has the characteristics of high strength, high chemical stability and thermal stability.It can resist the corrosion of high temperature, high pressure, acid, alkali, salt and various organic solvents.As the covering support material and tower packing of the catalyst in the reactor, its main function is to increase the distribution point of gas or liquid and support and protect the active catalyst with low strength.
Products include: grinding ball, heat storage ball and chemical filler ball. And 99 series, 90-92 series catalyst support ceramic balls and rings, 50-80 series catalyst support and components, and various ceramic ring products of 17-23 series and 23-33 series.The products have many advantages such as high strength, low wear, high hardness, good corrosion resistance, stable aluminum content and high compressive strength. They are widely used in minerals, iron and steel plants, thermal power plants, cement plants, petrochemical, natural gas, aluminum processing, chemical industry and environmental protection industries.More than 60% of the company's products are exported directly or indirectly to the Americas, the Middle East, Europe, Southeast Asia and other regions.
