The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material feeders, and the system for discharging the output product. The size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 0.5 to 3.5. The
My ball milling process ended up with agglomeration so I could not apply sieve analysis to measure particle size. I think that particle size was reduced dramatically after ball milling process ...
The results have revealed that the nano-sized amorphous silica particles are formed after about 6 h ball milling and they are spherical in shape. The average particle size of the silica powders is found to be around 70 nm which decreases with increasing ball milling time or mill rotational speed.
When it comes to long-term grindings of several hours with high energy input to obtain particle sizes 1 m, Planetary Ball Mills have been the instruments of choice so far. Despite their benefits for this type of application, they have the drawback of requiring cooling breaks and are not as easy to handle as mixer mills.
Laboratory Rod Mill Working Principle The laboratory rod mill is a rotating drum that causes friction and attrition between steel rods and ore particles. But note that the term rod mill is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for

Grinding materials to a nano-scale is an important aspect of quality control and RampD. AZoM speaks to Dr. Tanja Butt from RETSCH GmbH about the benefits of using High Energy Ball Mills instead of Planetary Ball Mills.
Abstract Size reduction is the operation carried out for reducing the size of the bigger particle into a smaller one by external forces. This reduction in size is done by using ball mill. In the experiment, the stone weighs about 300g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 80rpm.
