шлифовальные керамические

The allumina grinding balls has been widely used in ball mills as abrsion media for ceramic raw materials and glave materials in ceramic factories,cement factories,enamel factories and glass work owing to the extradinarily high density, high hardness,high wear resistance. During the abrasive or grinding process.ceramic balls will not broken.it will not contanminate the materials to be grinded. “QY-60”and “QY-75”density is moderate, the price is low, especially for architecture pottery and Sanitation pottery glaze machining. Their hardness is high, suitable for horniness material, suitable for horniness material machining, such as zirconite,glaze,Al2O3 etc. “QY-99”mainly used for no SiO2 pollution material. High abrasion, the abrasion loss is just 1/3 1/5 of the JC/T 848.0-1999, so can be substitute by the expensive ZrO2 ball in many grinding System.
