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.

  • faster and finer grinding than any other ball mill
  • speed of 2000 min-1 allow for ultra-fast pulverization of the sample
  • water cooling permits continuous operation without cool down breaks
  • temperature-controlled grinding
  • narrow particle size distribution thanks to special jar design which improves mixing of the sample
  • patented drive concept
  • easy operation via touch screen, 10 SOPs storable
  • operation with 2 grinding jars
  • easy installation of grinding jars
  • jars with integrated safety closure
  • range of jar materials allow for contamination free grinding

UNIQUE GRINDING JAR GEOMETRY

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism.

NO MORE COOLING BREAKS HIGHLY EFFICIENT COOLING SYSTEM

The greatest challenge when developing a high energy ball mill is keeping the temperature under control as the enormous size reduction energy leads to considerable heat built-up inside the grinding jar.

RETSCH solved this problem with an innovative integrated water cooling system. Hence, the Emax usually doesn’t require cooling breaks which are typical for long-term processes in conventional ball mills, even at low speed.

In the Emax the cooling system cools the grinding jars via the jar brackets. This is very effective because heat is more easily discharged into water than into air. The user can choose between 3 cooling modes: in addition to the internal cooling, the mill can be connected to a chiller or the tap to further reduce the temperature.

FUNCTION PRINCIPLE GRIND SIZES IN THE SUBMICRON RANGE

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.

The interplay of jar geometry and movement causes strong friction between the grinding balls, sample material and jar walls as well as a rapid acceleration which lets the balls impact with great force on the sample at the rounded ends of the jars. This significantly improves the mixing of the particles resulting in smaller grind sizes and a narrower particle size distribution than is possible to achieve in ball mills.



FOR SAFE AND EFFECTIVE GRINDING PROCESSES WIDE RANGE OF ACCESSORIES

GRINDING JARS IN 3 DIFFERENT MATERIALS

Available grinding jar sizes are 50 ml and 125 ml, materials include stainless steel, tungsten carbide and zirconium oxide, ensuring contamination-free sample preparation.

AERATION COVER

RETSCH offers a special aeration cover for the grinding jars designed for applications where a special atmosphere is to be maintained in the ball mill jar.

DIFFERENT GRINDING BALL SIZES & MATERIALS

The grinding balls are available in stainless steel, tungsten carbide and zirconium oxide. Sizes range from 0.1 mm to 15 mm, depending on the material.
