Advanced ball mills

A Review of Advanced Ball Mill Modelling † Lu s Marcelo Tavares 1 Department of Metallurgical and Materials Engineering, COPPE, Universidade Federal do Rio de Janeiro, Brazil Abstract In the early 1990s the discrete element method (DEM) was used for the first time to simulate media motion in tumbling mills

    Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced
