alumina ball

详情

As grinding media, high alumina grinding balls are widely used in the field of ceramics, cement, painting, chemical industry, medicine and dope. They have the following advantages&#****6; high hardness, high density, anti-corrosion, and regular appearance Specifications: 1) Al2O3: &#***5;*5% 2) Density: &#***5;3.7g/cm³ 3) EWT: &#***4; 0.*1% 4) Compressive strength: above 2,**0MPa 5) Water absorption: below 0.*2 6) Crushing strength: &#***5;**0kN 7) Hardness: 9 (MO) Alumina balls are available in following sizes: 1) Nominal sizes: 3, 6, *3, *9, *5, *8, *0 2) Bulk density range (kg/L): 1.6 to 2.5 3) Apparent porosity range (%): 1 to *0 4) Crushing strength range (kg): *0 to 1,6
