Grinding ball with high strength, high density, low wear, full specifications and applicability. Wildly used for ball mill, mixing mill, vibration mill and sanding machines and other equipment, widely used in construction ceramics, sanitary ceramics, alumina, zirconium, kaolin, refractory materials, paints, coatings and other fields. We have 2 type of production process to meet the customer's request, they are: Isostatic pressing and roll-forming: Isostatic pressing size range: D40-D70mm; Roll-forming size range: D1-D50mm
Grinding Balls are suitable for grinding medium used in ball grinding machines.

High strength,high wear-resistance,high hardness,large specific gravity,high temperature resistance ,high corrosion resistance .
1.Composed of quality alumina with high whiteness that does not compromise the quality of the grinded material.
2.Formed by rolling and isostatic pressure with high specific gravity .It significant raises the grinding efficiency,shortens the grinding time ,effectively increases the usable volume of the ball mill and thereby substantially extends the service life of the ball mill .
3.Low in abrasion,which greatly extends the service life of the ball ill
4.Can withstands high temperatures of more than 1000degree .It is resistant against acid,alkali and corrosion
Grinding ,polishing ball widely used in precision processing and deep processing of various ceramics ,enamels,glasses and thick ,and hard materials in chemical factories ,as grinding media for fine grinding machines like ball mills ,can-type mills and vibrations mills.
