The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

  • Effect of Slurry Solids Concentration and Ball Loading on .

    The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the results.
