Abstract: Nanopowder of hydrogen storage material will be widely used for fuel cell vehicle, and the other application fields of nanopowder are simply introduced. The fundamental principle of physically and chemically fabricating nanopowder in laboratory is analyzed respectively. The fundamental principle and system composition of mechanically ball mill for fabricating nanopowder in laboratory are expounded. The electric motor types, angular speed change in a revolution of stirring principal shaft, surface shape of principal rotation shaft and radial stirring teeth in the radial direction of stirring principal shaft, layer numbers of radial stirring teeth, stirring rod numbers in the every radial stirring layer, cross section shape of stirring principal shaft & radial stirring rod in the ball mill used for laboratory are primarily analyzed. The influence laws of AC servo motor driving way and different mechanical structure shape on steel ball dynamic response,ball flow fields properties and ball grinding effect for material powder are obtained. Electric drives and mechanical structure precept in ball mill are optimized.
