Process Engineering
Working Principle
- 1
Grinding beads receive kinetic energy from the mill agitator.
- 2
Collisions and shear between beads and particles break agglomerates and reduce particle size.
- 3
Bead density, size, roundness, and wear resistance determine energy transfer, separation behavior, and contamination risk.
Equipment Benefits

Frequently Asked Questions
What bead sizes and densities are available?
Bead diameter range is 0.05 - 3.0 mm depending on application. Yttria-stabilized zirconia beads are supplied in the standard size steps used by bead mills, with density and hardness matched to the mill type and the required fineness.
What is the zirconia content and wear rate?
High-purity yttria-stabilized beads are specified where contamination control matters, such as battery materials and electronic ceramics. Wear rate is confirmed against your mill duty rather than quoted as a single figure.
Which bead suits which mill and application?
Bead selection follows the mill separator opening, the target fineness and the material being ground. Typical duties cover Architectural Paints, Industrial Coatings, Printing Inks.
How do I choose between zirconia, glass and steel media?
Zirconia gives the best balance of density, wear resistance and contamination control for wet grinding. Glass is cheaper but wears faster; steel is denser but can contaminate light-coloured products. POLYC recommends from your fineness target and contamination limit.
How long do the beads last?
Service life depends on mill speed, product abrasiveness and media size. Beads are normally replaced as a batch when the grinding efficiency drops rather than on a fixed interval.
