RETSCH - High Energy Ball Mill Emax
High Energy Ball Mill Emax
General Information
The Emax is an entirely new type of ball mill for high energy milling. The unique
combination of high friction and impact results in extremely fine particles within the
shortest amount of time.
The high energy input is a result of an unrivaled speed of 2000 min-1 and the
optimized jar design. Thanks to the revolutionary cooling system with water, the
high energy input is effectively used for the grinding process without overheating
the sample. Due to the special grinding jar geometry, the sample is thoroughly
mixed which results in a narrow particle size distribution.
Unlike other high energy ball mills, the Emax is capable of continuous grinding
operation without interruptions for cooling down. This dramatically reduces the
grinding time. The high energy input in combination with the unique cooling system
provides perfect conditions for effective mechanical alloying or grinding down to the
nanometer range.
A wealth of safety features such as the integrated safety closure of the grinding jar,
temperature control with automatic start/stop system, and integrated imbalance
controls make operation of the bench-top mill Emax very user-friendly.
