Bynames: Ceramic ball, porcelain ball, grinding ball, corundum ball, wear-resistant porcelain ball, high-alumina ball
Appears as white balls ranging 0.5-95mm in diameter
Application: With its high strength, high hardness, high wear resistance, large specific gravity, small size, heat and corrosion resistant and pollution free, the product is 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 crushing machines like ball mills, can-type mills and vibration mills, with significantly higher crushing and milling efficiency and wear resistance than common ball stone or natural cobblestone.
Features:
(1)This product is composed of quality alumina with high whiteness that does not compromise the quality of the grinded material.
(2)This product is 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)This product is low in abrasion, which greatly extends the service life of the ball mill.
(4)This product withstands high temperatures of more than 1,000ºC. It is resistant against acid, alkali and corrosion.
