Posted by MSE Supplies on

MSE Supplies provides a broad range of products for ball milling of powders.  http://www.msesupplies.com/collections/powder-processing ------------------------------------------------------------------------------------------------------------------ The effect of grinding media performance on milling and operational behavior by U. Weber* and D. Langlois* Abstract: The effect of grinding media performance on milling and operational behavior was demonstrated under different selected conditions of calcium carbonate slurry milling. A variety of grinding media materials and bead sizes, along with two different stirrer tip speeds, were used in the grinding process to generate a particle size reduction of the calcium carbonate (CaCO3). To determine the optimum milling parameters the collected test data were used...
