Effect of lifters and mill speed on particle behaviour, torque, and ...

The power consumption of a ball mill is one of the most important parameters to consider in the design of a ball mill because it determines its economic efficiency. The power consumption is usually determined by charge fill level, lifter height, lifter number, and mill speed. However, almost all of the classical theories for calculating the ...

How Steel Charge affects Ball Mill Power Draw Grinding ...

No, it is not normal to operate above 40 to 45% charge level. Unless the trunnion is very small or unless you are using a grate discharge ball mill, balls will not stay in the mill, and you will spend a lot on steel to add a small amount of power. Formulas given for mill power draw modelling are empirical, and fit around field data over the ...

How to calculate the energy consumption of a ball mill? LinkedIn

The energy consumption of a ball mill can be calculated as follows: Measure the operating time of the mill. Measure the power input to the mill using a power meter. Calculate the energy ...
