High Efficient Middle Alumina Ball

Material: ≥ 92% Al₂O₃
Specific Density: ≥3.63 g/cm³
Size: 0.5-100mm
Model Number: KD-AL
Brand: KINGDA
Quantity:

                    123

● Description:

    Middle alumina ball is characterized by good crystallization, high content of aluminum oxide, high mohs hardness, high density, Low wear loss, etc., which greatly improves the grinding efficiency compared with traditional natural stone. Moreover, Using our middle alumina ball can save large amount of electricity compared with the natural stone due to its higher density.



  Feature:

1. Corrosion resistance, excellent rust resistance and intergranular corrosion resistance;

2. Wear resistance, good mechanical strength and ductility, high hardness, wear resistance and durability;

3. High temperature resistance, the use temperature limit can reach about 600 ℃;

4. Acid and alkali resistance, good corrosion resistance to alkali solution and most organic and inorganic acids;

5. High cost performance, cheaper than zirconia ceramics
