Acceleration of breakage rates of anthracite during
The breakage of anthracite in tumbling ball mills exhibits an unusual behavior of acceleration at fine levels of grinding. This phenomenon was discovered by using the selection function and the primary breakage distribution parameters to predict the size distribution of anthracite using the kinetics of grinding approach.

Ball Mills an overview ScienceDirect Topics
A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of

Ball Mill vs Coffee Grinder Pyrotechnics APC Forum
2010-1-11 Page 1 of 2 Ball Mill vs Coffee Grinder posted in Pyrotechnics: instead of ball milling, can I just use a number of different granite grinders to separately grind each chemical to a very fine dust, before I mix them by either the diaper method or mesh screens. Those little blade granite grinders work really well for Potasium Nitrate and Sulfur.
