Intuitive operation 1. Inserting the grinding jar 2. Closing the jar clamp 3. Operating the touchscreen

Functional Principle Unique size reduction mechanism produces grind sizes in the submicron range The High Energy Ball Mill Emax combines high- of the jars. This significantly improves the mixing of frequency impact, intensive friction, and controlled the particles resulting in smaller grind sizes and a circular jar movements to a unique and highly narrower particle size distribution than is possible effective size reduction mechanism. 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 course without changing...

Operation & Safety Safe handling of extreme forces Special focus was placed on operating convenience and safety when developing mill stops automatically and the remaining grinding time is displayed. the Emax. The grinding jar lids with integrated safety closure, which are simply Grinding parameters such as speed, time, interval operation or temperature screwed onto the jars, ensure absolute tightness for wet grinding processes or control are quickly and conveniently set via the color touchscreen. The in cases of pressure increase inside the jar. The grinding jars are quickly and temperature is...

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...

Faster – Finer – Coole

© FasterSubstantial time savingThe 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 ballmills. Another reason for shorter processing times is the highly effective size reduction mechanism employed in the Emax.Nano grinding of barium titanate Barium titanate is a ferroelectric material which belongs to the group of electrical ceramics and is used in areas like electronics and sensor technology. In this application example the requirement was...
