High Energy Ball Mills Instead of Planetary Ball Mills

The Emax is not a Planetary Ball Mill – it is much more. Higher speed, less warming, finer particles, faster grinding procedures. 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. To sum it up, the Emax is faster - finer ...
