Nanochalcogenides Fabrication By Ball Milling Pdf

This project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano powder. The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar.
