Alumina grinding balls and alumina filled balls are two commonly used alumina products. Although both are made of alumina materials, their application fields and functions are very different. In the following content, their similarities and differences will be explained in detail.
1. Different application fields
Alumina grinding balls are mainly used for grinding and crushing various materials such as ceramics, electronic materials, glass, chemical equipment, etc. Alumina filled balls are mainly used in tower plates, reactors and other equipment in the chemical, petroleum, power and other industries to increase the contact area of fillers and improve reaction efficiency.
2. Different functions
Another biggest difference between alumina grinding balls and alumina filled balls is their function. Alumina grinding balls are mainly used for grinding and crushing various materials to produce the desired particle size and shape. They move in the grinding groove, play a role of friction and impact, crush the material into particles of the desired size, and improve product quality and processing efficiency. On the other hand, the main function of alumina filled balls is to increase the voids and surface area within the device, increase the chance and efficiency of contact between reactants and catalysts, and improve the reaction speed and effect.
3. Differences in manufacturing processes
Although both are made of alumina, the manufacturing processes are different. During the processing, high-pressure molding and high-temperature sintering are required to produce alumina balls with good chemical stability, thermal stability, toughness, wear resistance and corrosion resistance.
4. Price difference
Alumina grinding balls and alumina filled balls have different prices due to different processes and scopes of use. Generally speaking, alumina grinding balls are more expensive than alumina filled balls.
5. Different corrosion resistance
Alumina grinding balls and alumina filled balls also have different corrosion resistance. During the friction and impact treatment of alumina grinding balls, part of the material surface is easily worn, and the surface layer is thin, so the corrosion resistance decreases. The main function of alumina filled balls is to increase the voids and surface area, so they have certain advantages in corrosion resistance.
In short, alumina grinding balls and alumina filled balls have obvious differences in application areas, functions, processes, prices, corrosion resistance, etc., and should be purchased according to specific production needs.
