99% Al2O3 3-50mm Ivory Beads Alumina Ceramic Ball for Grinding Equipmments
Grinding ceramic ball
It has been widely used in be suitable for use in high speed stirred grinding mills in mining applications.
And ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glass work owing to the excellence of high density, high hardness, and high wear rate.
during the abrasive/grinding processing,ceramic balls will not break up; it will not pollute the grinded material as well.
With small wear loss and high density, alumina grinding media are widely used in the mix and crush procedure of ceramics, glass,
glaze and frits, chemical and plastic industries.
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.
The alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the
grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
2.High bulk 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.
