The Secret Behind the Grindability and Polishability of Alumina Ceramic Balls
Alumina ceramic balls are now used as handles in the grinding media. From grinding ores, slurries, and wear-resistant materials to grinding powders, coatings, and paints, it has become an increasingly indispensable grinding medium. It is also widely used for polishing.
As a polishing material, spherical alumina is used because of its excellent wear resistance and roundness. It can avoid scratches and can more fully contact the polished object, so it is favored.
How to Solve the “Breaking Ball” Problem of Alumina Ceramic Balls
People who have been involved in the grinding industry probably know that alumina ceramic balls have problems with ball-breaking during application. Although it has a light bulk density, energy saving, low grinding temperature, and effectively improves grinding efficiency, the problem of “breaking the ball” has still become an obstacle in the promotion of ceramic balls. So how to solve this problem? By consulting the information and relevant experience of RS manufacturers, there are the following methods to deal with such situations.
- The toughness can be improved by adding toughening elements to the ingredient plan. In addition to being wear-resistant and impact-resistant, it can improve toughness and reduce the ball breaking rate under working conditions such as rolling sliding impact, and collision during the grinding process.
- The existing alumina ceramic ball forming methods include pressing and roll forming. Try to choose pressed balls. The compacted balls should have strong density and impact resistance, which can effectively reduce the breakage rate.
- Try to follow the standard process for grinding. For example, when loading and grinding in an empty chamber, add materials first and then add balls to alleviate the collision force and protect the ceramic balls. Filling the ball in an empty warehouse without adding material will easily cause micro-cracks in the ceramic balls due to collision during the process of falling into the mill, which will affect the service life of the alumina balls.
There will always be some problems in the application of alumina ceramic balls, but with our careful operation and careful summary, these problems will be gradually solved.
