Charge behaviour and power consumption in ball
200181 Typical power consumption for a 5m diameter by 7mlong ball mill is between 2.5 and 3.5 MW. The actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 1–5%.

Charge behaviour and power consumption in ball
Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed. The effects of changes to the properties of the charge (ball fraction ...

MATERIAL GRINDING BY MEANS OF BALL MILLS
2019219 ball mill consists of a cylindrical steel drum (with the size of 2 to 5 m in diameter and 3 to 15 m in length) and steal balls (up to 25 cm in diameter) inside of it (see Fig. 1). The drum is being rotated by means of an electric drive (with power consumption of up to 1 MW). The raw material is fed into the mill at the inlet side of the drum by means of a feeder and the grinded material is taken away at the outlet

Scale‐up of power consumption in agitated ball mills ...
Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.
