ZirPro provides the optimum combination of efficient and cost-effective zirconia-based products to enhance productivity and quality. Composed of either stabilized zirconia — Zirmil® Y and Zirmil® Ce — or zirconium silicate materials — ER120 and Rimax® — ZirPro’s wide range of durable ceramic grinding beads help achieve more controlled operations.
Agrochemical formulations tend to be low-viscosity, temperature-sensitive suspensions of active chemicals. These crop-science products include pesticides and fertilizers. The target for grinding in agrochemicals applications is to ensure that exact particle size distribution is achieved. Coarse particles are prohibited as they can clog the spraying nozzles, and ultrafine particles are not desired either as they increase absorption rates.
Saint-Gobain ZirPro has been supplying high-quality ceramic media for agrochemical applications for more than 40 years. ZirPro ER120 beads between 0.8 mm and 1.25 mm are the industry standard in horizontal mills. Higher-density Zirmil®Y can deliver increased efficiency. In this case and to prevent heat generation, smaller bead sizes need to be combined with higher flow rates.
The ability to run long and problem-free production while limiting downtime and the loss of active compounds is a key requirement for agrochemical processing applications. ZirPro zirconia beads provide the stability to ensure that mills perform to expectations. ZirPro also offers a unique level of after-sales and technical support to keep processing running smoothly.
Highest specification and quality standards
Widely used in horizontal mills (typically 200 liters),
ZirPro's 4.0 g/cc density ER120 beads are the ideal milling solution, especially as an alternative to glass beads. Rimax® beads are recommended when larger-size beads are required for less friable products.
With a 6.0 g/cc density, the Zirmil line provides the most cost-effective, long-term solution due to its improved energy efficiency and extended media life.
