Ball Milling Process Ppt

  • Production of Gold

    The Ball Mill B 101 grinds the 0.25 ore until it is in the range of 160 microns The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles The top stream leaving the cyclone is 75 of the feed into it This top product is 160 microns or less.

  • Production Methods for Carbon Nanotubes Including Arc

    May 16 2006  The milling is carried out at room temperature for up to 150 hours Following milling the powder is annealed under an inert gas flow at temperatures of 1400°C for six hours The mechanism of this process is not known but it is thought that the ball milling process forms nanotube nuclei and the annealing process activates nanotube growth.
