Ball Mill Principle, Construction, Working, and More

High-quality ball mills are potentially expensive and can grind mixture particles to as small as 0.0001 mm, enormously increasing surface area and reaction rates. Factors determining the efficiency of ball mill: The degree The Moores group has recently shown a dependency of milling materials on results of BM and indicated that effectiveness of BM depended on both Vickers hardness (VH) of the milling balls and their mass. 15 VH of 440C steel is ∼760 MPa at low temperatures, significantly lower than that of the stainless-steel (SS) balls that were Choosing the right strategy: cryogrinding vs. ball milling
