The energy efficiency of ball milling in comminution
Similarly, the net efficiency of the ball mill will have the same value, in this case, for any monosize feed to the ball mill at any other size distribution, that is, any other X 50 of the product, since the lines for singleparticle breakage and ball mill grinding are parallel.

A study of comminution in a vertical stirred ball mill.
Using a 5 litre batch mill, an experimental programme was designed to study the comminution characteristics of the stirred mill. A factorial design was prepared with the following parameters, which influence grinding in the stirred ball mill: pulp density, pin tip velocity and ball density and size. The energy required for grinding the chromite sand in the stirred ball mill was determined by

Comminution '16: a very successful conference
The particle sizes that can be fed to a ball mill depend on the ball size distribution of the charge and more specifically, the diameter of the makeup ball. This is also a function of the tenacity of the particles as this controls the size at which the selection function is maximum for a given ball charge. Particles that are larger than the size at which the selection function is maximum are
