Functional Principle Unique size reduction mechanism produces grind sizes in the submicron range The High Energy Ball Mill Emax combines high- the rounded ends of the jars. This significantly frequency impact, intensive friction, and controlled improves the mixing of the particles resulting in circular jar movements to a unique and highly smaller grind sizes and a narrower particle size effective size reduction mechanism. distribution than is possible to achieve in ball mills. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular...

Highly Efficient Cooling System makes cooling breaks obsolete The greatest challenge when developing a high breaks which are typical for long-term processes in The user can choose between 3 cooling modes: energy ball mill is keeping the temperature under conventional ball mills, even at low speed. in addition to the internal cooling, the mill can be control as the enormous size reduction energy connected to a chiller or the tap to further reduce leads to considerable heat built-up inside the In the Emax the cooling system cools the grinding grinding jar. RETSCH solved this problem with jars...

Faster Substantial time saving The high maximum speed of 2000 rpm and the fact that the water cooling system allows for grinding without breaks in most cases result in time savings of up to 90  when using the Emax compared to % conventional ball mills. Another reason for shorter processing times is the highly effective size reduction mechanism employed in the Emax. Time advantage in pharmaceutical research A small particle size has a positive effect on the bioavailability of orally taken active ingredients. The Emax pulverizes pharmaceutical samples and ingredients to submicron and...
