99.9% High Purity Alumina Bead
High-purity alumina ceramic grinding ball is a high-quality grinding medium made of selected high-quality raw materials and subjected to high temperature firing through isostatic pressing technology.
With high strength, high hardness, high abrasion resistance, large body, high temperature resistance, corrosion resistance and pollution-free. Excellent use Deep processing and finishing of thick and hard materials are grinding media for fine grinding equipment such as ball mills, vibration mills, and pot mills. Either dry or wet.
Product Application: Ball mills for ceramics, mining, cement, paint, chemicals, medicine, coatings, refractories, mining and other industries.
Our high-purity alumina ceramic grinding balls have the following characteristics:
1: The composition is mainly composed of high-quality alumina (99.9%), with high whiteness, which does not affect the quality of the grinding material. And the hardness is large, exceeding 1800HV10, the mechanical strength is high, exceeding the wear-resistant steel. It has no effect on the quality of the material being ground.
2: Using isostatic pressing and rolling forming, the specific gravity is large, the grinding efficiency is greatly improved, the grinding time is reduced, and the effective volume of the ball mill is effectively increased, thereby increasing the amount of grinding materials.
3: Good abrasion resistance. Its abrasion resistance is equivalent to 266 times of manganese steel and low wear. Compared with steel grinding media, it can greatly extend the service life of the grinding body by more than 10 times.
4: Can withstand high temperature of more than one thousand degrees, and has the characteristics of acid resistance, alkali resistance and corrosion resistance.
5: The grinding medium has a large body density (≥3.60g / cm3), which can greatly improve the grinding efficiency, reduce the grinding time, save energy consumption and reduce costs; at the same time effectively increase the effective volume of the ball mill, thereby increasing the amount of grinding materials. And the advantages of regular shape, easy classification, high grinding efficiency, and favorable price;
6: We have developed a special ball for dry grinding with good toughness and low wear, which solves the problem of contamination of raw materials by the grinding medium commonly existing in the powder industry.
