velocity profile of a ball mills

  • Coupled DEM CFD Model to Predict the Tumbling Mill

    Axial center of mass profile The velocity vector profile is shown in figure 10, the axial center of profile of the mill is calculated by locating the center of circulation along different axial length. The center of mass profile can be used to calculate the net power draw using the traditional torque arm approach.

    Ball Mill Critical Speed. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range. Pebble

    Grinding Ball Mills. Ball Mills are generally used to grind material 1/4 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.
