Application Area:

Sediment samples preparation

This products are very easy to use, just put the balls inside the jar and attached them to the grinding machine. Make my sample preparations much easier and faster.

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 innovative jar design. Thanks to the revolutionary water cooling system, 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.


  • Faster and finer grinding than with any other ball mill
  • Speed of 2000 min-1 allows for ultra-fast pulverization of the sample
  • Water cooling permits continuous operation without cool down breaks
  • Narrow particle size distribution thanks to special jar design which improves mixing of the sample
  • Easy operation via touch screen, 10 SOPs storable
  • Patented drive concept
  • Range of jar materials allow for contamination free grinding
