Alumina grinding balls & lining bricks series

””””To catch the home and abroad customers”Æ rapid increasing demand of grinding media, we develop three series of grinding balls and lining bricks with high alumina balls series: 92% and 95% alumina; Micro-crystal medium-alumina balls series: 65%~75% alumina and Silicon carbide high alumina balls: 60~70% alumina( also called brown medium alumina balls). The customers can choose the best series that most suitable for them according to the produce demand. The detailed information please refer to the TABLE-1,TABLE-2 and TABLE-3.

Characteristics : High alumina & Micro-crystal medium alumina

”ō””High wear-resisting: The alumina balls”Æ wear-resisting is higher than the common ceramic balls”Æ. When it is working, the ball will not pollute the grinded materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
”ō””High density: the high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
