The surface area per unit mass is called the specific surface. To calculate this in a known mass of material it is necessary to know both the particle size distribution and also the shape factor of the particles. The particle size gives one dimension that can be called the typical dimension, D p, of a particle. This has now to be related to the ...

Posted 21 October 2006 - 04:24 PM. Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.
