The ultra-centrifugal mill from Retch has a proven track record of over 20,000 units delivered worldwide, establishing it as the de facto standard. With exceptional performance, flexibility, ease of use, and robustness, this high-speed rotor mill is recognized as the top runner in its class. The highly anticipated new product, the ultra-centrifugal mill ZM300, can instantly grind samples using a rapidly rotating rotor and a ring-shaped screen on the periphery, providing both convenience and safety in the working environment. We are pleased to introduce this long-awaited new product online. Topics • Features, operating principles, and accessories of the ultra-centrifugal mill ZM300 • Tips and tricks • Cryogenic grinding with the ultra-centrifugal mill • Comparison of applications: grinding particle size, sample discharge rate, grinding temperature • Cleaning and handling Speaker Retch Product Manager, Nao Ninomiya

The powder characteristics of raw materials (cement, aggregates, fly ash, and other additives) for concrete and mortar, which are construction materials, are very important as they greatly influence the strength and durability of structures such as stadiums, condominiums/apartments, highways, bridges, and dams. In this webinar, we will introduce handling techniques for cement and aggregates, including particle size reduction and sieving, as well as evaluation techniques for the physical properties of powder and granular materials. - LECHE (Wader Scientific Co., Ltd.): Particle size reduction, sieving, electric furnace - Microtrack Bell Co., Ltd.: Particle size distribution, particle shape, specific surface area, pore distribution, true density, surface characteristics We welcome not only those who are already involved in construction materials but also those who wish to learn more. By responding to the survey after the webinar, you will be able to download the presentation materials.
