After the speeds of the driving disc and the driven disc are synchronized, the load torque of the motor is equal to the load torque of the ball mill. Although the theoretical friction torque still increases, as shown by the solid line in the Figure 7, the friction torque that the air clutch transmission is equal to the load torque of the ball mill. In addition, with the rotational speed and angle of the barrel increase, the material begins to cascade and fall, which causes the load torque …

Nov 12, 2013 · BALL MILL SIZE IS 4.4*11 M. GRINDING MEDIA SIZE IS MAX 30MM . IT IS A MONOCHAMBER MILL DESIGNED TO GRIND THE ROLLER PRESS PRODUCT. IF WE CALCULATE THE SHAFT POWER WITH 28% FILLING IT COMES TO MORE THAN 2600 KW WITH 210 T GRINDING MEDIA. ALSO 28% FILLING DO NOT CORRESPONDS TO 180 T MEDIA , IT IS MORE THAN 210 T
Learn MoreThe DEM results are shown to be highly consistent with the experimental results. The torque of liners and baffles are affected by lifter height, lifter number, and mill speed. Moreover, the changes in the torque and power consumption of a ball mill can be effectively explained using two important factors: lifter and particle area ratio
Learn MoreThe basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
