High Hardness Alumina Ceramic Grinding Balls with 9 Mohs Hardness and 92% Alumina

92% alumina content endows it with stable hard foundation. After high-temperature sintering at 1600 ℃, the compactness of the sphere reaches over 98%, with no internal pores; A Mohs hardness of 9 can easily handle materials with a hardness of ≤ 7 (such as feldspar and iron ore), with a compressive strength of up to 180MPa, and is not easily cracked during milling. Third party testing shows that after continuous grinding of ceramic bodies for 30 days, the wear rate is only 0.06%, far lower than the level of 0.3% for ordinary grinding balls; And the surface roughness Ra of the sphere is ≤ 0.6 μ m, which reduces material adhesion during milling, ensures no debris pollution, and guarantees the purity of the processed material. ​
