Cost-Effective, Durable & Optimised for Large-Volume Bead Mills
The Cell Lab SZS Milling Media are medium density sintered zirconium silicate beads, manufactured from premium zircon (ZrSiO₄) using a high-temperature sintering process. With excellent breakage resistance, smooth sphericity, and competitive pricing, these beads are ideal for large-volume agitated bead mills. Offering an optimal performance-to-price ratio, SZS beads are widely chosen for fine grinding and dispersion applications where cost efficiency and durability are equally critical.
High-quality sintered zirconium silicate – Produced from premium zircon (ZrSiO₄) under controlled high-temperature sintering.
Medium density & cost-effective – Perfect balance between grinding efficiency and price advantage for bulk use.
Outstanding durability – Excellent breakage resistance and long media lifespan, even in high-intensity mills.
Perfect sphericity & smooth surface – Fully dense, defect-free beads ensure uniform grinding and consistent dispersion.
Versatile bead sizes – Wide range from 0.4 mm to 14 mm, enabling precise matching to different grinding requirements.

Cell Lab SZS milling beads are designed for large-volume bead mills and suitable for:
Fine grinding & dispersion of zircon and other minerals
Large-scale pigment & dye production
Ceramic slurries & coatings
Paints, inks & surface treatments
Chemical processing requiring cost-efficient media
Q1: What makes SZS beads different from high-density zirconia beads?
A: SZS beads offer a medium density and lower cost, making them ideal for large-volume processes where price efficiency and durability are key. High-density zirconia beads provide more grinding power but at higher cost.
Q2: What bead sizes are recommended for large-volume bead mills?
A: Larger beads (4–14 mm) are generally used in large-scale, high-throughput mills. Smaller beads (0.4–2 mm) are suited for fine dispersion in medium-volume or specialised processes.
Q3: Are SZS beads resistant to breakage?
A: Yes. They are fully dense, non-porous, and manufactured through a high-temperature sintering process, giving them excellent breakage resistance.
Q4: Can they be used for grinding zircon specifically?
A: Yes. These beads are the recommended choice for efficient fine grinding of zircon materials.
Q5: What industries benefit most from SZS media?
A: Pigments, ceramics, coatings, chemical processing, and mineral grinding industries that require durable yet cost-efficient media for large-scale operations.
