  • Grinding Media Charge Motion inside Mill

    THEORY OF VON STEIGERCASCADING MOTIONTHEORY OF DAVISCATARACTING MOTIONThe first important modification to the above treatment was suggested by von Steiger; who pointed out that the hypothesis of free flight of the particle along the ascending branch of the parabolic trajectory is invalid since the continuous projection of material along any trajectory results in contact between the particles. Thus for the ascending branch of the parabola the speed along the arc is constant; not variable as is the case with free flight of particles.On referring to Fig. 2.9, it iLive Chat
