Ultra centrifugal mill for size reduction of soft and medium-hard materials
Achieve precise particle size reduction and consistent sample preparation across various materials with our high-speed grinder, optimized for rapid and gentle processing—even for temperature-sensitive substances.
Processes and Pulverizes Materials at High Speed
The Ultra Centrifugal Mill ZM 300 from Retsch GmbH is a versatile rotor mill designed for high-speed size reduction of soft to medium-hard materials. It employs an impact and shearing principle to efficiently pulverize samples, maintaining sample integrity with minimal temperature increase. Ideal for applications ranging from agriculture and food processing to pharmaceuticals and polymers, the ZM 300 delivers precise and consistent results. The mill features a variable speed range of 6,000 to 23,000 rpm, allowing customization for different material requirements. It supports batch and continuous operations, integrating seamlessly into existing production lines. Equipped with an integrated temperature sensor, the ZM 300 ensures reproducibility and optimal process control. Its stainless steel and titanium construction offer durability and resistance to wear, while easy-to-clean components minimize downtime. The ZM 300 accommodates various sample sizes, with options for cryogenic grinding for sensitive materials. Compliance with relevant industry standards and extensive customization options further enhance its suitability for specific research and industrial needs.
