2019-4-18  This was reduced to 479.2 nm, 412.2 nm, and 440.7 nm by the disintegration, which lasted for 30 min. The measurements were 328.2 nm, 518.7 nm, and 715 nm after the disintegration continued for 60 min. The 90 min of the duration of disintegration yielded the measurements of average particle size of 557.2 nm, 666.4 nm, and 757.5 nm.

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming

Grinding Down to the Nanoscale with Planetary Ball

The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating "sun" disk that rotate in the opposite direction around the disk centre. Because of this, the samples are quickly and effectively comminuted by impact, frictional and shear forces resulting from ball-to-wall and ball-to-ball collisions.

Various particle size distributions, cannot be uniform in desired nano size; all or larger particle sizes may still exist in a significant percentage. Product recovery : after milling, the next challenge is the separation of the milled sample from the small grinding balls (for large grinding balls it is easy, but for very small grinding balls* it could be difficult).
