Earlier work by Fuerstenau and Kapur on the comminution of quartz in a singleparticle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.
It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill, towards optimum production of material in the desired size class, there is a need to correlate the ball size and the feed size distributions.
Cody Layton Scharffen Berger Chocolate Maker Case 1. The ball mill has potential to be a major step forward in meeting the rising demand for quality chocolate produced by Scharffen Berger. The ball mill has the ability to reduce the particle level of the chocolate from one hundred microns to twentyfive microns in just three hours, instead of the forty to sixty hours that this process takes ...
