1.The Alumina Ceramic Grinding Ball 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
