Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder as the chamber rotates the media is lifted up on the rising side and then cascades down from near the top of the chamber.
Ball milling technique using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys in fact ball milling process is not new and dates back to more than 150 years it has been used in size comminutions of ore mineral dressing preparing talc powders and many.
Ball mills are generally used to grind material 14 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 various classifiers such as screens spiral.
