The mill outside diameter The mill out side diameter is a function of the grind ing process selected Autogenous mills are the largest in diameter since the feed grinds itself A semi autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller Ball mills are smaller still and use a larger
End Mills Ball Nose End Mills Ball End Mills A ball end milling cutter is also known as a ball nose mill The end of this tool is ground with a full radius equal to half of the tool diameter and the edges are center cutting They can be single end or double end and they can be made from solid carbide or various compositions of high speed
Finer particle size in the overflow there is thus less material in the overflow This implies material in the under flow which is the fresh feed to the second ball mill If circulating load in the second ball mill is kept constant any variation in the fresh feed will ultimately be reflected in the product particle size
