The advantage of our zirconia bead (EZ-BEAD)
High Dense‧Small Grain Size
Near nano zirconia powder is used for the grinding beads to achieve almost theoretical density, hardness and toughness. Together with special forming process, our YSZ beads have superior micro-structure and physical properties which provides extreme wear resistance and life-time for high speed milling process.
Always Shiny Surface Condition
Shiny surface throughout life-time results from high dense internal structure and stable chemical composition. It reduces friction between bead-bead and bead-grinding chamber which benefits temperature control, energy saving, and avoiding damage of the chamber inner wall. On the other hand, always shiny beads are easy to clean which provides time saving when changing product lines and minimizes cross contamination as well.
Superior Roundness and Narrow size distribution
Size distribution and roundness of the beads play the key contribution of milling efficiency.Our YSZ beads, with roundness
over 96% and precise sieving size control, provides best the milling efficiency.

Purpose : To analyze the beads (Ceno bead from famous Korea bead maker ) that sent by customer
Brief :
Compare with beads that provided by LK Inter, customer’s sample ( Ceno-bead) has poor density and crushing load which will lead to bead breakage during high speed milling. This is due to “hole” inside the bead body.
The surface condition and roundness of beads that provided by customer are also much worse that that by LK Inter. Poor surface smoothness and “egg-like” beads tend to cause high friction which results in high wear of the machine and high temperature of the milling slurry.
Beads provided by LK-Inter has wider distribution than customer’s. It is due to the distribution can be controlled by sieving , it can be adjusted.
