Grinding Media FAQs – Yttrium Stabilized Zirconia (YTZ)
Who manufactures EMI’s YTZ grinding media?
EMI Mills is an authorized distributor of Saint-Gobain ceramic grinding media. Yttrium stabilized zirconia (YTZ) grinding media supplied by EMI is manufactured by Saint-Gobain and meets established quality, consistency, and performance standards.
What is Saint-Gobain?
Saint-Gobain is a global manufacturer of advanced ceramic materials and industrial solutions, including high-performance grinding media used in wet media milling and bead milling applications across multiple industries.
Why purchase Saint-Gobain grinding media through EMI instead of direct?
Purchasing Saint-Gobain grinding media through EMI provides access to application support, equipment expertise, and milling process guidance in addition to product supply. EMI supports customers with media selection, bead sizing, testing, and integration with EMI milling equipment, helping reduce trial-and-error and improve process outcomes.
What is yttrium stabilized zirconia (YTZ) grinding media?
Yttrium stabilized zirconia (YTZ) grinding media is a high-density ceramic bead used in wet media milling and bead milling applications. Yttria stabilization improves toughness and wear resistance, making YTZ suitable for high-energy milling conditions.
What bead size should I use for YTZ grinding media?
Bead size selection depends on factors such as target particle size, formulation viscosity, and milling energy. Smaller beads are typically used for finer particle size reduction, while larger beads provide higher impact energy for more aggressive milling. EMI can provide guidance based on your specific process requirements.
Is YTZ grinding media suitable for high-viscosity formulations?
Yes. Due to its high density and durability, YTZ grinding media is commonly used in higher-viscosity systems where increased milling energy and stable media circulation are required. Our Grinding Media Overview can assist with additional info.
Does YTZ grinding media introduce contamination into the product?
YTZ grinding media offers low wear rates compared to lower-density media, which helps minimize contamination in sensitive applications. Media selection should still consider material compatibility and allowable contamination levels for the process.
How long does YTZ grinding media typically last?
Media life depends on operating conditions, formulation abrasiveness, and milling intensity. In general, YTZ grinding media provides extended service life in high-energy milling applications due to its wear resistance and toughness.
Can YTZ grinding media be mixed with other bead sizes or media types?
Mixing bead sizes or media types is generally not recommended, as it can lead to inconsistent milling behavior and uneven energy distribution. Most processes achieve more repeatable results using a single bead size and media material.
Is YTZ grinding media compatible with all EMI media mills?
Yes. YTZ grinding media is compatible with the full range of EMI wet media milling equipment, including laboratory, pilot, and production-scale media mills.
How is YTZ grinding media packaged?
YTZ grinding media is typically supplied in 20 kg plastic containers. Smaller quantities may be available in 1 kg increments depending on bead size and availability.
How do I request pricing or availability for a specific bead size?
Pricing and availability can be requested by contacting EMI directly. Pricing, availability, process recommendations… our team can assist with it all.
