Zirconia ceramic beads is made from super
material and advanced technical craft and suitable for any kinds of
mills such as micro-mill, attritor-mill, vibratory mill and ball
mill to grind and disperse effectively and economically the
material of electronic slurry, ceramic powder, magnetic material,
battery material, rare-earth material, nonmetal ore, painting, dye,
ink, calcium, titanium, pesticide, food stuff and medicine etc.
Comparing with other grinding media such as Alumina media, zirconia
silicate media, steel media, agate media and glass
media,zirconia ceramic bead has high density and
toughness and super hardness, so it has better grinding
efficiencies. The high wear-resistantzirconia ceramic
bead prevents materials
from being contaminated and chemical etching or short service life
of the grinder.
These
special features make TZP grinding media especially suitable for
material grinding in important occasion.
