HIGH ENERGY BALL MILL
Retaining bracket
Faster and fi ner grinding than with any other ball mill
Grinding jar
Speed of up to 2,000 min-1 provides ultra-fast pulveri- zation of the sample
Safety screw
Innovative water cooling permits continuous opera- tion without cool down breaks
Narrow particle size distri- bution thanks to special jar design which improves mixing of the sample
Fig. 2: The grinding jar brackets are mounted on two discs each which turn in the same direction. As a result, the jars move on a circular course without changing their orientation. The quadruple eccentric drive ensures the precise anti-synchronous movement of the grinding jars. Mass forces are eliminated by integrated counterbalances.

FUNCTIONAL PRINCIPLE
The novel size reduction mechanism of the Emax unites the advantages of different mill types: high-frequency impact (mixer mill), intensive friction
play of jar geometry and movement causes strong friction betwee balls, sample material and jar walls as well as rapid acceleration which lets the balls impact with great force on the sample at the rounded ends of the jars. This signifi cantly improves the mixing of the particles resulting in smalller grind iz and a narrower particle size distribution than achieved in ball millls.

(vibratory disc mill) and controlled circular jar movement (planetary ball mill) allow for unrivaled grinding performance. This unique combination is generated by the oval shape and the movement of the grinding jars. The grinding jar brack- ets are mounted on two discs each which turn in the same direction. As a result, the jars move on a circular course without changing their orientation. The i int we
