Ultra centrifugal mill for size reduction of soft and medium-hard materials
In analytical and industry-focused laboratories, achieving rapid and precise size reduction of soft to medium-hard materials is crucial. Challenges often include maintaining sample integrity and preventing heat-sensitive materials from degrading during the grinding process.

Achieve precise size reduction and maintain sample integrity
The Ultra Centrifugal Mill ZM 300 by Retsch is a high-performance mill designed for rapid and reproducible size reduction of soft, medium-hard, and fibrous materials. With a variable speed capability from 6,000 to 23,000 rpm, it allows precise control over the grinding process, preventing excessive temperature rise and preserving sample characteristics. The integrated temperature monitoring system ensures consistent results, while a wide array of rotors, ring sieves, and cassettes provides flexibility for various size reduction tasks. Ideal for applications in the food, chemical, and agricultural industries, the ZM 300 can handle sample volumes up to 4.5 liters with the optional cyclone system. Users can expect enhanced throughput and finer particle sizes, especially beneficial for fibrous and plastic materials.
