High energy untra fine ball mill
Achieve ultra-fine particle sizes rapidly with this high energy milling solution, designed to deliver unrivaled grinding precision and efficiency while maintaining temperature control—ideal for complex material processing in research and development settings.
The Emax from Retsch GmbH is a high energy ball mill specifically designed for ultra-fine grinding applications. Unique in its category, the Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to rapidly achieve target particle sizes in the submicron range.
Ideal for sectors such as pharmaceuticals, ceramics, and metallurgy, it produces stainless steel powders, ceramic tiles, and organic compounds with precision. With two grinding stations, it accommodates jars from 50 ml to 125 ml, enabling batch processing for both dry and wet grinding. The water-cooled system allows for continuous operation by effectively dissipating heat generated during milling, eliminating the need for cooling breaks typical of traditional ball mills.
The Emax’s sophisticated GrindControl system monitors and maintains optimal temperature and pressure, enhancing process accuracy and repeatability. In terms of efficiency, its variable-speed motor vastly reduces energy consumption. All components in contact with materials are available in stainless steel, tungsten carbide, or zirconium oxide, ensuring chemical compatibility and minimizing contamination.
Additionally, the Emax integrates seamlessly with laboratory data systems via USB and LAN interfaces, while its robust construction and CE certification underscore its safety and reliability. Designed for ease of maintenance, it supports quick jar and ball changes to maximize uptime, delivering unparalleled support for demanding research and development environments.
