Two basic limitations are inherent in conventional milling systems. These limitations are, first, the inability to perform ultra-fine grinding economically and, second, their failure to produce uniform particle size distribution.
The Vibro-Energy principle of applying high frequency, three dimensional vibrations to a chamber containing small cylindrical grinding media helps to overcome both of these limitations. It takes less total energy to reduce or break a small particle than it does a large one. For ultra-fine grinding, only very small impact forces are necessary. Any force in excess of that needed to break the material results in wasted energy which will be dissipated as heat. In addition, the greater the number of grinding impacts per unit of time, the faster a given particle size reduction can be accomplished. Therefore, the Vibro-Energy Grinding Mill, using small amounts of energy with high frequency vibration, is more efficient than the high impact, low-frequency principle applied in conventional grinding systems.
In most industries which process finely ground materials, uniform particle size is of utmost importance. However, this close particle size distribution has been extremely difficult to achieve with ball and pebble mills. In th elower micron range, their point contact offers decreasing probability of further particle reduction and increasing probability of wide particle size distribution
Zeitgeist invokes the mood of the age and perhaps no feeling more closely reflects this spirit of the time than that we must salvage our planet.

Rainbows and sugar may conjure up images of a certain leprechaun-branded breakfast cereal. But now, researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart that displayed multiple colors when stretched by hand. When evenly stretched with a simple apparatus, the material enhanced the unique shifts in fluorescence intensity of 14 sugars tagged with a dye, distinguishing between them in beverages and sweat samples.
