GRINDING AND SHAPING METHOD USING VERTICAL GRINDING MILL

A grinding and shaping method using a vertical grinding mill, comprising: selecting a vertical grinding mill with thread pitch/diameter ratio of a spiral rotor; selecting the grade of a grinding medium and determining the filling factor and adding the grinding medium into a grinding chamber of the vertical grinding mill; sequentially initiating a dust collector, an air blowing device, a driving device and a feeding device, wherein the driving device propels the spiral rotor to rotate, and the air blowing device blows upward from bottom of the grinding chamber; adjusting rotation speed of the spiral rotor of the vertical grinding mill to change cycling speed of the raw material and the grinding medium in the grinding chamber; feeding a raw material into the feeding port at an upper end of the grinding chamber; initiating a discharging device, and discharging the raw material from a discharging port.
