Ball Milling Method Process
High energy ball milling process for nanomaterial synthesis It is a ball milling process where a powder mixture placed in the ball mill is subjected to highenergy collision from the balls This process was developed by Benjamin and his coers at the International Nickel Company in the late of 1960 Email contact.Jun 15 2012 Advantages of ball milling process 1 Nanopowders of 2 to 20 nm in size can be produced The size of nanopowder also depends upon the speed of the rotation of the balls 2 It is an inexpensive and easy process Disadvantages 1 As the process is not so sophisticated therefore the shape of the nanomaterial is irregular.In this paper the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry number and size of balls and speed of the mill were modelled and discussed Simulations through discrete element method (DEM) provide correlation between the milling parameters A mathematical model is used to improve and develop this process.
