Milling reduces these to primary particles— the product—which themselves are susceptible to aggregation. Once primary particles form, additives are required to keep them suspended. "It's important to remember that the goal is particle size reduction, not particle destruction," Stummer says.
· According to commonly accepted milling guidelines, mill jars of this size should be turning at about 8090 RPM for optimum milling efficiency. I won't bore you with mathematical details, but the simple way to accomplish an increase of jar speed from 60 RPM to that optimal speed is to increase the drive roller's diameter from its current 1/2inch diameter up to 3/4inch diameter.

validity of each theory within a certain particle size range. This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm). Rittinger's law showed more _app1icability to the fine
Laboratory ball mills are scaleddown ball mills that use milling jars that are filled with grinding media and rotated using a jar rolling mill to reduce the particle size of the material. While they are commonly used for small size appliions, options are available that can also be used for larger production opportunities. Long Roll Jar Mills
