Chat OnlineEffect of mill speed on the energy input in this experiment the overall motion of the assembly of 62 balls of two different sizes was studied.The mill was rotated at 50, 62, 75 and 90 of the critical speed.Six lifter bars of rectangular cross-section were used at equal spacing.The overall motion of the balls at the end of five revolutions is shown in figure 4.As can be seen from the.
Chat OnlineThe theoretical predictions of roll torque and separating force are compared with actual measured data.The result reveals that the proposed solution is appropriate for solving broadside rolling, and the roll torque and separating force are in good agreement with the actual measured ones since the maximum errors are less than 15.
Chat OnlineA mill ready to start a grinding operation could be around 150 t in dead weight.Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it.Figure 8.11 illustrates a typical change in torque with increasing speed of motor.It can be seen that the peak torque of 140 of the running.
