Alumina Grinding Open Hole Balls
How does the alumina ceramic hammer come from?
The wear-resistant ceramic hammer is made by making a small hole in the alumina ceramic ball and inserting a customized steel bar. The main characteristics of alumina ceramic balls are high strength, high hardness, high wear resistance, large ratio, small volume, high temperature resistance, corrosion resistance, less pollution and other excellent characteristics. Alumina ceramic balls are widely used in the finishing and deep processing of thick and hard materials in different types of ceramics, glazes, glass, chemical plants. Compared with ordinary pebbles or natural goose soft stones, its wear resistance is better. Moreover, the alumina ceramic hammer head is resistant to more than 1000 degrees of high temperature. Its service life is also ten to twenty times higher than that of cast stone, wear-resistant alloy cast steel, steel plastic, steel rubber and other materials, which can bring greater economic benefits into play.
