Inert Packing Balls

Advantages

Our products can be applied to multiple production processes, including raw material crushing, fine grinding, and pneumatic conveying, to meet the wear resistance requirements of different equipment. Customers can reduce communication and coordination among multiple suppliers through unified procurement, while also facilitating the matching of grinding media and equipment lining performance, reducing abnormal wear caused by material incompatibility.
The alumina grinding medium uses high-purity alumina, which is precisely shaped and sintered at high temperatures to form a dense structure that can withstand continuous impact and friction. During long-term operation, its wear is low, which helps maintain stable grinding efficiency and reduces downtime and maintenance costs caused by frequent replacement of grinding media.
Alumina ceramics have stable chemical properties and are not easily reactive with most processing materials. The wear particles generated during use are mainly composed of alumina, which can reduce the risk of other impurities entering the material. Therefore, it is particularly suitable for production processes that require high whiteness, purity, and finished product performance.
We have established a quality control system from raw material inspection, production process to finished product testing, and continuously monitor key performance. Controlling the performance deviation of different batches of products within 2% helps maintain a stable wear rate and grinding effect. For continuous production, this consistency can reduce process parameter adjustments and improve the stability of production management.
The high wear resistance and chemical erosion significantly reduce the frequency of industrial equipment replacement. It can reduce maintenance downtime, protect downstream catalysts, and lower overall costs.

Application 

Inert alumina ceramic balls are widely used in various industrial fields due to their chemical stability, thermal stability, and high mechanical strength. In the petrochemical industry, inert alumina ceramic balls are used in refining, catalytic cracking, hydrogenation refining and other units as catalyst support beds to prevent catalyst particle loss, optimize fluid distribution in reactors, and protect precious metal catalysts. In the chemical industry, such as synthetic ammonia, methanol, ethylene and other chemical production, it can be used as a filler in fixed bed reactors to improve heat and mass transfer efficiency. In the fields of environmental protection and exhaust gas treatment, such as flue gas desulfurization and catalytic combustion of volatile organic compounds, it can be used as a catalyst carrier to extend the service life of the catalyst. In the pharmaceutical and food industries, due to its pollution-free and non leaching characteristics, it has become an ideal filler for the synthesis of pharmaceutical intermediates, food grade solvent refining, and other fields.
