If a ball mill contained only coarse particles, then of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as …
Robust Model Predictive control of Cement Mill circuits
The present work considers the control of ball mill grinding circuits which are characterized by non-linearities and disturbances. The disturbances are due to large ariationsv and heterogeneities in the feed material. Thus the models obtained by simple tests on these mills are subject to large uncertainties which may result

Pharmaceutical Technology: PRACTICAL I : BALL MILLING
A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.

Ball Milling - an overview | ScienceDirect Topics
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
